Scientific calculators were first introduced in the 1960s. The first scientific calculator was produced by Hewlett-Packard (HP) in 1964. Since then, scientific calculators have become an integral part of math and science education. Math and science teachers use scientific calculators to teach their students how to solve math problems, including calculus, algebra, geometry, trigonometry, and statistics.

The scientific calculators are used in schools, colleges, and universities worldwide. A scientific calculator can do many different things, including:

- Scientific calculators can perform basic arithmetic operations like addition, subtraction, multiplication, division, square root extraction, percent calculation, etc.
- Scientific calculators can perform more advanced operations like complex number calculations, matrix operations like finding determinants and inverses of matrices, etc.
- Scientific calculators can perform trigonometric operations like sine, cosine, tangent, arc sine, arc cosine, arc tangent of any angle or of the sides of any right triangle.
- Scientific calculators can find the roots of any polynomial. They can find the solutions of equations like quadratic (quadratic formula), cubic (Cramer’s rule), etc. Scientific calculators are also capable of performing statistical operations like mean, standard deviation calculation, probability calculation, Chi-square distribution calculation etc.
- Scientific calculators are capable of performing exponential and logarithmic functions like natural logarithm (log), common logarithm (log base 10), inverse logarithm (1/x), etc.

In this article, I am listing the 5 best scientific calculators in India with a buying guide.

## Purchase Guide-Best Scientific Calculator

### 1. Worked in Functions

Other than comprehending complex increases, subtractions, duplications, and divisions, and the scientific calculator ought to be equipped for performing parallel, hexadecimal, and octal estimations, parts, logarithms, likelihood, insights, and so forth.

### 2. Battery/Solar and Battery

While every single essential calculator is battery fueled, some top-of-the-line models additionally have sunlight-based force reinforcement which guarantees a more drawn-out battery life.

### 3. Convenience

It is ideal to pick a lightweight and convenient calculator that fits effectively in the pocket or sack and can be conveyed to classes and workplaces.

### 4. Solidness

While designers may need to utilize their scientific calculators in the fields, understudies may need to convey it to their classes, labs, and workshops. Thus, it is critical to pick a number cruncher that is hearty and strong and has an enormous screen that shows clear figures even in the sun.
