Type any arithmetic expression and see it solved step by step following PEMDAS — Parentheses, Exponents, Multiplication & Division, then Addition & Subtraction. Every operation is highlighted as it happens.
Use × or *, ÷ or /, ^ for powers. Supports decimals and parentheses.
P → E → M·D → A·S
PEMDAS tells you the order in which to perform operations so every mathematician gets the same answer. Without it, 2 + 3 × 4 could mean either 20 (wrong) or 14 (right).
Multiplication and Division share the same priority — work through them left to right. Same goes for Addition and Subtraction.
8 ÷ 2(2 + 2) ≠ 1 → it = 16
Students often trip on these patterns:
12 ÷ 4 × 3 is (12 ÷ 4) × 3 = 9, not 12 ÷ (4 × 3) = 1.2 × 3² is 2 × 9 = 18, not 6² = 36.-3² means -(3²) = -9, not (-3)² = 9.Getting tripped up by order of operations? One-on-one Algebra 1 tutoring walks you through every rule with real examples — so PEMDAS clicks once and for all.
