❓ Frequently Asked Questions
The order is BODMAS/PEMDAS: Brackets first, then Orders/Exponents, then Multiplication and Division (left to right), then Addition and Subtraction. Our Evaluate tab follows this automatically.
(a+b)² = a² + 2ab + b². For example, if a=3 and b=4: (3+4)² = 9 + 24 + 16 = 49. Use the Expand tab to try any values with full step-by-step working.
Prime factorization means expressing a number as a product of prime numbers only. For example 360 = 2³ × 3² × 5. Use the Factor tab — enter any number to get the full prime factorization and all factor pairs.
