How to Calculate General Math
What is General Math?
General math calculators cover core arithmetic operations: percentages, ratios, GCD, LCM, prime factorisation, rounding, and number properties.
Formula
- X
- X/100 × Y — X/100 × Y
- Y
- X/100 × Y — X/100 × Y
Step-by-Step Guide
- 1Percentage: X% of Y = X/100 × Y
- 2GCD: Euclidean algorithm — repeatedly apply modulo
- 3LCM(a,b) = a × b / GCD(a,b)
- 4Prime check: test division by primes up to √n
