This simple approach helps users solve equations accurately without manually remembering the sequence of operations.

Understanding the Order of Operations

The order of operations is a set of rules that defines the correct sequence to evaluate a mathematical expression. The standard sequence is often remembered using the acronym PEMDAS:

  • P – Parentheses first
  • E – Exponents (powers and roots)
  • MD – Multiplication and Division (left to right)
  • AS – Addition and Subtraction (left to right)

Why Order of Operations Matters

Without a proper order, the same expression can yield different results. For example: 8+2×58 + 2 \times 58+2×5

  • Incorrect (left-to-right without order): (8 + 2) × 5 = 50
  • Correct (order of operations): 8 + (2 × 5) = 18

The Order of Operations Calculator ensures you always follow the correct sequence, eliminating errors.

Example of Using the Order of Operations Calculator

Example 1: Basic Expression
Expression: 3 + 6 × (5 + 4) ÷ 3 − 7
Step-by-Step Calculation:

  1. Parentheses: (5 + 4) = 9
  2. Multiplication/Division: 6 × 9 ÷ 3 = 18
  3. Addition/Subtraction: 3 + 18 − 7 = 14
    Result: 14

Example 2: Expression with Exponents
Expression: 2^3 + 4 × (6 − 2)
Step-by-Step Calculation:

  1. Parentheses: (6 − 2) = 4
  2. Exponents: 2^3 = 8
  3. Multiplication: 4 × 4 = 16
  4. Addition: 8 + 16 = 24
    Result: 24

Example 3: Complex Expression
Expression: (10 + 2)^2 ÷ (6 − 4) × 3
Step-by-Step Calculation:

  1. Parentheses: (10 + 2) = 12, (6 − 4) = 2
  2. Exponents: 12^2 = 144
  3. Division: 144 ÷ 2 = 72
  4. Multiplication: 72 × 3 = 216
    Result: 216

These examples show how the calculator handles complex expressions efficiently and accurately.
