If you went to a higher level when it comes to mathematical calculations and mathematical equations, then you probably need something more than the classic Calculator. You should try the Scientific Calculator because it will offer you an easier way to calculate a lot of things, even if in the beginning they look strange and very hard to use or understand.

## How to use the Scientific Calculator?

Firstly, before starting to go into details you should learn the basics. It was the same thing when you had to learn the basic math operations like the subtraction, multiplying, addition or division. After you mastered these operations you were able to do more complicated equations.

Depending on each model, the Scientific Calculators, both the online one and the real one that people like engineers keep in their pockets, can have different operations and functions, but most of them include the essential Algebra, Geometry, Calculus, Trigonometry.

If you’re not familiar with the Scientific Calculator’s functions and operations, you can take a look to the following list of operations and symbols and you’ll know what mathematical operation will result if you’ll use some of them:

**+** Addition

**–** Subtraction (not negative)

**x** Multiplication (There is often an x key for variables as well)

**÷** Division

**^** Raise to the power of

**√ or Sqrt** Square root

**y^x** y to the power of x

**ex** Exponential

**sin** Sine function

**cos** Cosine function

**sin-1** Inverse sine function

**cos-1** Inverse cosine function

**tan** Tangent function

**tan-1** Inverse tangent function

**log** Log base 10

**ln** Log to the base of e

**(-)** or neg Denotes negative number

**π** Inserts pi

**()** Parentheses for denoting order of operations

**Mode** Switches between degrees and radians

## Why a Scientific Calculator will help you?

Maybe you’re wondering why you should try to use a Scientific Calculator, and the answer is simple: because it will make your job much easier and you’ll be able to calculate long equations and other things just by tapping some buttons.

In the beginning it might be a bit complicated when you’ll try to enter a longer equation, and you’ll have to make sure that you’ll respect the order and the importance of each operation before using the Scientific Calculator’s functions.

Using the () symbols will make it easier because this way the users are able to decide and to “teach” the Scientific Calculator which of the entered operations is the most important. Don’t forget to insert one or more parentheses because this is an essential step.

Users will have to prioritize some of the operations. To do that, as we said before, people can use the parentheses and everything will work perfectly.

As an example, if you’ll have to type something that looks like this: 7^2/(25-(6/3+3*4)), it is very important to use the correct syntax otherwise you’ll get a wrong result, and this isn’t due the fact that the Scientific Calculator works wrong but because you didn’t entered the desired equation.

Once you’ll understand how to combine the functions and how to use everything that this Scientific Calculator has to offer, your life will be much more easier when you’ll have to calculate Trigonometry functions or something else that a normal calculator can’t do.

It is important to know that there are different types of Scientific Calculators, and some of them might have double functions for the same button. If you’ll see something like Fn or Shift, it means that you can switch between the functions of a button.

Another cool feature for most of the Scientific Calculators is the restore option. Using a Scientific Calculator that has this feature on your PC will help you a lot when you’ll have to deal with large numbers and complicated equations.

There are also some calculators that offer you a full history of the latest operations that you made, and this is also very helpful when you want to remember exactly how you calculated something and what was the exact result. Comparing these things with a classic calculator you’ll realize why it is much more easier and effective to use a Scientific Calculator for complicated operations.
