## Definition

A scientific calculator is an advanced computational tool designed to solve complex mathematical, scientific, and engineering problems. Unlike basic arithmetic calculators, it supports trigonometric functions, logarithms, exponents, root extractions, and order-of-operations evaluations using parentheses. It handles scientific notation for extremely large or small numbers and allows switching between degree and radian modes for geometric calculations. Students, engineers, and scientists use this tool for algebra, calculus, physics, and chemistry computations.

## How to Use

1. **Enter expression** — Type or click buttons to enter your mathematical formula into the input area.
2. **Set angle unit** — Toggle between degrees and radians if your calculation involves trigonometric functions.
3. **Press calculate** — Click the equals button or press enter to solve the expression.
