Math Calculator

Basic arithmetic calculations with advanced functions

Quick Guide

  • • Basic Mode: Select operation and enter numbers
  • • Expression Mode: Type expressions like "10 + 20" or "√25"
  • • Square Root: Use √ symbol or select in basic mode
  • • Percentage: Use % symbol (e.g., "25%" = 0.25)

How to Use the Math Calculator

Basic Mode

  1. Enter your first number in the "First Number" field
  2. Select the mathematical operation you want to perform
  3. Enter your second number (if required) in the "Second Number" field
  4. The result will appear automatically as you type
  5. Click "Clear" to reset all fields and start a new calculation

Expression Mode

  1. Switch to "Expression Mode" using the toggle at the top
  2. Type your mathematical expression directly (e.g., "25 + 15" or "√64")
  3. Click "Calculate" to see the result
  4. Supported operators: + (addition), - (subtraction), * (multiplication), / (division), ^ (power), √ (square root), % (percentage)

Understanding Math

A math calculator is an essential tool for performing basic arithmetic operations quickly and accurately. Whether you're balancing a budget, calculating tips, or helping with homework, understanding basic mathematical operations is fundamental to everyday life.

Basic Arithmetic Operations

  • Addition (+): Combining two or more numbers to get their sum
  • Subtraction (−): Finding the difference between two numbers
  • Multiplication (×): Repeated addition of a number
  • Division (÷): Splitting a number into equal parts

Advanced Operations

  • Exponentiation (^): Raising a number to a power (e.g., 2^3 = 8)
  • Square Root (√): Finding a number that, when multiplied by itself, gives the original number
  • Percentage (%): Expressing a number as a fraction of 100

This calculator supports both basic mode for simple calculations and expression mode for more complex mathematical expressions, making it versatile for various mathematical needs.

Formula & Calculation Method

Mathematical Formulas

Addition

a + b = sum

Example: 5 + 3 = 8

Subtraction

a − b = difference

Example: 10 − 4 = 6

Multiplication

a × b = product

Example: 6 × 7 = 42

Division

a ÷ b = quotient

Example: 20 ÷ 4 = 5

Exponentiation

a^b = a × a × ... (b times)

Example: 3^4 = 81

Square Root

√a = b, where b² = a

Example: √16 = 4

Percentage

a% = a ÷ 100

Example: 25% = 0.25
