How To Use A Scientific Calculator For Mathematics

Since we can't do mathematics like a breeze, there's a savior for us who makes the process a lot easier. And that is the Scientific Calculator. Read this blog post to gain insights on how to use a scientific calculator for mathematics.

Mathematics is a term that terrifies many of us! Well, there's also some genius out there who solves complicated equations like a breeze! But not all of us have that superpower, still, no matter how much we try to avoid mathematics, it never stops to follow us. Nowadays, mathematics is required not only as an education institution, but also in workplaces as well, either it's a business or a job. Since we can't do mathematics like a breeze, there's a savior for us who makes the process a lot easier. And that is the Scientific Calculator. We can solve almost all kinds of daily needed mathematical equations through a scientific calculator. Although many of us sometimes struggle to use it, as it has so many options and sign languages! But nothing to worry, because once you learn how to use the functions and understand the meaning of different signs, you'll be able to solve equations like a pro!

How to Use a Scientific Calculator

Meaning of different labels on the buttons

First, let's explore the meaning of various signs and labels that we see on the calculator. Knowing their names is the first step of learning to use a scientific calculator.

Know how the functions works

As we've got the idea of which symbol means what, now it's time to understand how to use them to get our desired result.

Applying power to a number

For taking or applying power to a number, you've to enter the number first. And then look for (^) this sign. Press this button and then enter. For instance, if you want to calculate, then you have to enter 4^2 and then press the enter button. There're also symbols such as x2 or y3, in that case, you have to enter the number of which you want to calculate and press those symbols. But the only limitation here is you can only get the result for power 2 and three with this function. But by using the first way, you can use any number.

Square root

Square root function is pretty simple. The square root of 4 is 2, 9 is 3, etc. To calculate this first, enter the root (√) symbol, then the number and press enter. You'll get the result.


Trigonometry functions are known as SIN, COS and TAN. It helps us to understand the angles, such as a degree or radius. But with these functions, you can either know the value of different degrees of SIN, COS or Tan or convert different values into a degree. For instance, SIN 30-degree has values of 0.5. To calculate that, press SIN, the 30 and enter. The result will be 0.5. However, if the result shows -0.988, then your calculator is set on radian mode. You can change it by pressing the MODE key.


If you want to run a calculation with the same precedence, it'll be conducted from left to right, and the parentheses operations will perform first. However, the innermost set of parentheses are performed first if parentheses are nested. Remember that parentheses are always correct.

A few basics

As you've got the idea of how the functions work, there's another thing you need to know. In a scientific calculator, you'll see some symbols are in yellowish, and others are in dark pink. To apply those particular functions you've to use SHIFT and ALPHA buttons. For yellowish characters, you've to press the SHIFT button first and then any of those symbols. And for dark pink characters, you've to press ALPHA first and then those symbols.

Tips & Tricks for Financial or College Mathematics

As now you have learnt how to use a scientific calculator, you want to introduce a few tricks and tips by which you can solve your equations more easily during exams.
#1 Converting numbers into scientific notations
Converting a large number is a complicated task, and most of the time, we make mistakes here. One common mistake like this is counting multirole zeros wring! But you can easily do this by pressing the ENG button. It converts the number into notations. But remember you can only calculate a number that can be divisible by 3 of the power 10.
#2 Save/store numbers
Do you know that you can store small equations or mathematical rules in your scientific calculator? If no, then let's learn the technique. First, enter an equation or rules in the calculator using different functions, and then follow the step- SHIFT=>RCL=>hyp. And your entered formula is stored! But remember not to ON, or else your previous works will be lost.
#3 Getting the polar form of complex numbers
Complex numbers can be expressed in two ways, polar form (Rcis(θ)) Cartesian form (a + bi). For instance, if you have a Cartesian form, such as 1+i then converting it into a polar form can be done by using the Pol button. It'll save your time and extra stress!

Bottom Line

We hope that you've now got the idea of how to use a scientific calculator. We've also shown some tricks and tips. But to become fluent in using a calculator you've to do a lot of practice. And no one knows that maybe someday you'll invent your very own tips and tricks! Happy learning!
