Then you will require a solution that is more suitable to tackling the challenging issues you are facing. A what is a scientific calculator tool that will do the trick. In addition, if you are going to enrol in a math course that is more advanced in the near future, your instructor will most likely ask you to make use of a scientific calculator.

At the conclusion of this post, we’ll take a look at three HP scientific calculators that have different price points, but before we do that, let’s take a closer look at precisely what a scientific calculator is and go over five different tasks that you may use it for.

What is a scientific calculator?


What is a scientific calculator, in contrast to its more basic electronic calculator cousins, are capable of performing the same operations, but in addition, they provide a wide variety of other capabilities. On the market today, you may purchase calculators that fall into one of three primary categories: business, basic, or scientific.

It is quite conceivable that you have previously used a simple calculator when you were taking math classes in high school, and it is even possible that you have used a business or graphing calculator when you were taking a course in economics or business statistics.

what is a scientific calculator, on the other hand, is the only one that is capable of performing specific operations in a variety of disciplines, including trigonometry, physics, chemistry, and engineering.

A scientific calculator contains additional capabilities that enable you to deal with exponents and logs, both of which demand more memory in order to execute operations in the most efficient manner and get the best possible results.

Although you can also perform fundamental calculations with this calculator, such as addition, subtraction, multiplication, and division, these operations are really the tip of the iceberg in terms of the kinds of problems it is able to solve.

What is a scientific calculator – The Step-by-Step Guide to Using a Scientific Calculator

Reading the handbook is the most straightforward approach to become familiar with using the calculator. If you purchased a calculator that did not come with an instruction manual, you can typically find the model online and download a copy of the handbook for free. If this is not the case, you will need to do some experimenting; otherwise, you will input the correct numbers but still receive the incorrect result. what is a scientific calculator this is that many calculators each have their own unique way of processing the order of operations. For instance, if the result of your computation is:

3 + 5 * 4

You are aware that, in accordance with the order of mathematical operations, the 5 and the 4 ought to be multiplied by each other before the addition of the 3. This is something that your calculator might or might not know. When you enter the calculation 3 plus 5 times 4, some calculators will give you the result 32, while others will give you the result 23. (which is correct). Investigate the functions of your calculator. If you see a problem with the order of operations, you have two options: you can either type in 5 times 4 plus 3 (to get the multiplication out of the way) or you may use parenthesis to add 3 plus 5. (5 x 4).

In a scientific calculator, what characteristics are most important to search for?

If you plan on taking any courses that go into topics such as geometry, scientific notation, trigonometry, engineering, or physics, then it is quite probable that you will be required to learn how to operate a scientific calculator at some time in your academic career.


It is not reasonable for you to anticipate spending more than $200 on your scientific calculator. In point of fact, HP sells three products for under $60, two of which cost less than $15. Because of the additional capabilities that are included, you should budget a little bit more money than you would for a standard or business calculator.


There is a good chance that the labels for your functions will be different depending on the manufacturer. They ought to be able, for the most part, to carry out the same responsibilities. If you still have access to your syllabus, look it over to make sure that you are purchasing the choice that was suggested for you to get.

Included as a bonus

There have been some significant advancements made to scientific calculators over the past few years. Although you do not need to have the most expensive model in order to pass your course, you should be aware of these changes. These include access to Wi-Fi as well as the option to share your work with your instructor or fellow students.

Here are the top five applications for a scientific calculator, as well as some examples of how you could be asked to utilise one in your next course.

  1. Primitive mathematical operations and exponents

Perform mathematical operations as fundamental as addition, subtraction, multiplication, and division with a calculator. You need to keep in mind that the sign for subtraction (-) is not the same as a distinct negative function in each given situation. Because the signs for positive and negative numbers are so similar to one another, using a calculator for the first time might result in some misunderstanding regarding the difference between the two types of numbers.

Exponents, as well as undetermined quantities


In addition to using the negation operator, you can also obtain the square root of a formula or integer by raising it to a higher power.

However, only a scientific calculator is capable of performing any algebraic calculation, even though exponents are utilised in virtually every math subject taken after elementary school.

You can use your calculator to solve for a number that you already know, but you can also use it to solve for a number that you don’t know. This will be helpful for algebra as well as any other type of more complex mathematics that you could be learning.

The chronological order of events

Scientific calculators enable you to input a problem that contains an order of operations, but basic calculators only allow you to solve simple equations with one or two variables. Basic calculators are useful for solving equations with one or two variables. If you were to enter any of these equations into a standard calculator, it would not be able to discern which numbers need to be worked on first in the right manner.

On the other hand, if you punch in the equation into a scientific calculator, it ought to give you the appropriate response after you do so. This is due to the fact that there is an option for parentheses, which enables you to tackle more complicated issues. This instructs the calculator to carry out that operation first, much like what would happen if you were carrying out the calculation manually on paper.

  1. Root of square

You may also use a scientific calculator to get the square root of a number, which is one of the easiest calculations you can carry out. This operation is also one of the most straightforward. After you enter the number and press the SQRT key, you will see the answer display.

Which is more important: Both options are now open to you.

In many cases, the only thing that is required to discover the solutions to equations is the use of one or two keys, which may make the process of solving tough issues both quicker and simpler.

Even though the vast majority of teachers now promote the use of calculators in their classes, it is still a good idea to inquire beforehand as to whether or not this kind of equipment is permitted. The use of a scientific calculator is beneficial to a large majority of people.

  1. Using Logarithms

what is a scientific calculator have gained more information and are gaining new understandings connected to calculus and trigonometry, it is possible that you will be required to study about logarithms. You may use these formulae to compute things like speed and area, among other things.

In the past, practically all of these activities were carried out by hand. Inputting the appropriate data into a calculator and finding a solution to the problem takes only a few seconds at this point.

Facilitated medical care and technological advancements

Logarithms are utilised most frequently in the domains of medicine and engineering; nevertheless, professionals in a variety of other professions may, at some time, come into contact with them. Solving them by hand might be challenging, but doing it with the assistance of a scientific calculator can make the job far less difficult.

In most of your classes, your device will most likely be able to solve for the natural logarithm of an equation. Because all that is required to understand logarithms is understanding how to enter the appropriate formula into a scientific calculator, some educators choose to limit their explanations to this method alone.

Memory is essential to the process of solving logarithms.

what is a scientific calculator might want to think about utilising a scientific calculator for logarithms is the fact that these calculators are equipped with an internal memory that enables the user to save certain formulae.

You have the option of telling your calculator to save the information that you have previously entered into the device if the task you are working on will need more than one session to complete. This makes it simple for you to return to whatever you were doing if you feel the need to take a break or if you want to experiment with different permutations.

  1. Calculations based on the sine, cosine, and tangent functions

Sine functions are expected to be understood by students enrolled in a trigonometry or calculus class. If your job path involves any kind of architectural or technical sector, you will likely see them rather frequently.

When trying to determine the measurement of a certain angle, particularly in cases when the other sides or angles are unknown, a sine function might be utilised. There is also a possibility that you may come across the inverse sine, which is a method that is frequently applied when determining the hypotenuse of a triangle.

This computation, much like logarithms, used to take a while to solve since you had to go from one sheet of paper to the next as you worked. Once you have entered the function in a scientific calculator in the correct manner, you are able to obtain the answer practically instantly. On every calculator, you should check for buttons labelled “sin,””cos,” and “tan” to ensure that it has these capabilities.

Drawing a graph of the sine

The graphing of a sine is an additional computation that can be required of you in this context. This is a straightforward approach to present your work, and many schools now require you to be familiar with the process of graphing a variety of functions.

Cosine functions

You may also graph and solve for cosine functions, much like the previous example. The length of a triangle is most commonly measured using the cosine of an angle, which is a measurement that is most commonly employed in trigonometry classes. Finding the length of the hypotenuse of a triangle would most certainly need the use of cosines, and a scientific calculator may also perform the calculation in the other direction using inverse cosines.

Cosines are able to be calculated for any angle, regardless of how big or negative it is. Again, you could be asked to produce a graph using your calculator in order to demonstrate that you are familiar with the concept of cosines.

Tangents in degrees or radians

Tangents are another another subject that will be covered in a trigonometry course, and just like the last one, this one will need you to locate unknown numbers. When computing the distance between two perpendicular lines in geometry, you will most certainly come across tangents.

In trigonometry, you will utilise it to determine the value of the side that is opposite the values that have been supplied. In addition, you have the option of receiving your response in either degrees or radians, depending on the specifications provided by your instructor.

Again, the only form of calculator that can determine the answer to these kinds of problems is called a scientific calculator, and it is quite possible that at some time in your education you will be required to use one of these calculators. This may be especially relevant in the event that your instructor asks you to demonstrate that you are familiar with graphing particular functions, which may be a component of your overall mark.

what is a scientific calculator to check that the radian mode on your calculator is not selected if you want the results to be shown in degrees. Doing so will throw off your equation and provide you with a result that is completely different from the one you are searching for.

  1. Scientific notation

A scientific calculator is useful for more than just solving increasingly difficult mathematical problems. In point of fact, the capability to compute scientific notation may be one of its most valuable uses. A standard calculator won’t be able to handle values that are too large to be expressed using decimal points due to the fact that they can’t be written in that format.

If you want to work in an industry that is connected to science, engineering, or mathematics, then you will almost certainly make use of scientific notation, and you will unquestionably want a more complicated calculator in order to complete your assignments.

It’s not nearly as difficult as you would think to enter scientific notation on a calculator, in case you were wondering. For the purpose of carrying out the operation:

  • Find the 10 x on your device and click it.
  • Enter in your x value

To view the solution, you must first activate the “Enter” button on your keyboard.

In contrast to standard calculators, which are limited to working with numbers on a smaller scale, scientific calculators are capable of working with numbers on a much larger scale. This capability can be beneficial when it comes to the process of data collection as well as when working in the fields of chemistry and calculator. It can also compute negative scientific notation.

There is a specialised mode that can assist those who are interested in pursuing a career in engineering in calculating equations that are particular to their chosen profession. You’ll find it on your device as the ENG display mode, and it’s purpose is to facilitate the communication of numerical information both verbally and in written form.

  1. Binary operations and functions

A scientific calculator is able to solve for binary functions in a manner that is analogous to the manner in which you would enter equations into your calculator to compute notations or logs, tangents, and sines. These equations require two variables to be entered.

You will most often run across this while you are solving for an unknown in algebra or calculus, but you might also talk about it when you are learning about the Cartesian product and subsets.

what is a scientific calculator another type of equation that is difficult to keep track of if you do not have a calculator with memory. This is due to the fact that if you are able to store the results that the calculator gives you, you will be able to build off of the work that you have already accomplished or save your efforts for another time.
