### What is a scientific calculator?

Different types of calculators are available for solving math’s problems. Some companies also offer calculators which can be used for general purposes along with the study of mathematics and science.

### Basic requirement while using scientific calculator for math’s

There are two types of scientific calculators, one which is used for the simplification of math’s problems and other which can be used to solve problems related to trigonometry, geometry and algebra.

To use a scientific calculator for solving math’s problems, the basic requirements are as follows:

1. The mathematical problem which has to be solved should be typed in the calculator using correct syntax.

2. The direction of keys on the calculator should be kept as same as the direction on a standard calculator.

3. The input key of the scientific calculator has to be pressed first, followed by the mathematical operator key.

4. Wrong input should be checked thoroughly before getting started on a problem, since this can lead to wrong calculation.

5. Wrong input should be corrected immediately to avoid any incorrect result.

6. Different types of storage functions are available on a calculator such as memory and register.

7. A scientific calculator can also be used to solve problems related to geometry, algebra and trigonometry.

Scientific calculators can be used for general purpose to solve problems related to operations, roots and fractions. This type of calculator is useful when a problem requires a number of steps to be performed.

In mathematics, a scientific calculator can be used to solve problems related to square roots and other roots, operations with fractions and polynomials, algebraic expressions and other types of functions.

These calculators can be used to solve problems related to logarithms, trigonometric equations and exponential functions.

### Importance of scientific calculator in math

Equations with a scientific calculator are commonly used in maths, physics and other sciences. In fact, even some calculators created for mathematics can solve equations containing roots or indeterminate.

In more advanced maths, a scientific calculator can be of great help in solving complex problems, where the steps required to solve them manually would be too time–consuming, tedious and inaccurate.

A scientific calculator is also used as a tool for checking solutions to more complicated problems. In high school, a scientific calculator may be used in different ways:

- Either as a standalone tool, to solve problems on its own, without having to use paper and pencil; or as part of a learning management system (LMS), to solve the more complicated problems of mathematics; or finally, to learn how to use it.

A scientific calculator is important in maths for all of these reasons. It can do a lot more than a normal calculator and definitely makes the process of learning math’s a lot easier. In fact, in high school math, students are constantly required to make use of it in order to solve problems. It is most commonly used in trigonometry, calculus and statistics:

#### Calculus

#### Statistics

Other subjects where a scientific calculator can be useful include physics, chemistry and algebra.

Some calculators have more advanced functions than others and can be used in higher math classes and for engineering and other related fields. Be aware that not all calculators are good for everyone, as some have a different view. Try before you buy to make sure it will work the way you want it to.

Calculators designed for engineering and sciences usually have buttons that make the steps of calculations easier; these calculators may also have advanced functions, such as conversion between units.

Although a calculator may have many advanced functions, it is important to understand the basic functions as well. In some cases, it may be easier to use a low-tech calculator for simple tasks, such as adding and subtracting.

Study the guide books and manuals that come with your calculator to find out exactly what functions it has and how to use them before you begin your calculations.
