Fractions
A fraction represents a part of a whole, \(\frac{numerator}{denominator}\). To add or subtract fractions, use a common denominator. Multiply fractions by multiplying numerators and denominators respectively; divide by flipping (reciprocal) the second fraction and multiplying.
\(\dfrac{a}{b} + \dfrac{c}{d} = \dfrac{ad + bc}{bd}\)

Example: \(\dfrac{1}{2} + \dfrac{1}{3} = \dfrac{3+2}{6} = \dfrac{5}{6}\).
