Scientific Calculator

The scientific calculator is designed to perform both basic and advanced mathematical operations. It works like a normal calculator for addition, subtraction, multiplication, and division, but it also includes special functions such as square root, logarithm, natural log, trigonometric operations (sine, cosine, tangent), powers, and constants like π and e. Each button is linked to a function that appends a symbol or a number to the input line. When you press “=”, the calculator evaluates the whole expression using JavaScript math functions and returns the result. This makes it useful for solving school, college, or real-world math problems.
