Fraction operations formulas
The algorithm of this fractions calculator is based on the following formulas:
- Fraction addition = (AD + BC) / BD. Please note that in case of addition and subtraction between two or more fractions you first have to ensure all of your fractions have the same numerator.
- Fraction subtraction = (AD - BC) / BD
- Fraction multiplication = AC / BD
- Fraction division = AD / BC
