Math Expression Calculator

Introduction to the Math Expression Calculator

The math expression calculator is a web-based tool that instantly computes the result of a math expression you enter. It supports basic arithmetic operations, common math functions, and constants, with a clean and intuitive interface that suits students, teachers, or anyone who needs quick calculations.

How to Use the Math Expression Calculator?

1. Enter an expression: type the math expression you want to compute in the "Expression" text box, for example:

• 3 + 5 * 2
• (4 + 5) * 6
• 2 ^ 3 + sqrt(9)
• sin(30) + cos(60)
• log(100)

2. Compute: click the "Calculate" button or press Enter in the input box. The result is displayed in the "Output" text box.
3. Use an example: if you are unsure about the input format, click the "Example" button to fill in a random sample expression, then click "Calculate" to see the result.

Supported Operators and Functions

Basic operators:

• + addition, e.g., 3 + 5
• - subtraction, e.g., 7 - 2
• * multiplication, e.g., 4 * 6
• / division, e.g., 10 / 2
• ^ exponentiation, e.g., 2 ^ 3 = 8
• () parentheses, e.g., (3+5)*2

Math functions:

• sqrt(x) square root, e.g., sqrt(9) = 3
• sin(x) sine (radians), e.g., sin(Math.PI/2)
• cos(x) cosine (radians), e.g., cos(0) = 1
• tan(x) tangent (radians), e.g., tan(Math.PI/4)
• log(x) base-10 logarithm, e.g., log(100) = 2
• ln(x) natural logarithm (base e), e.g., ln(Math.E) = 1

Math constants:

• π pi, approximately 3.14159...
• e the base of natural logarithms, approximately 2.71828...
