How is adding/subtracting rational expressions similar to adding/subtracting fractions?

When we multiply fractions, we multiply the numerators and multiply the denominators. That is

𝑎 𝑐

𝑎𝑐

𝑏 𝑑

𝑏𝑑

. =

, 𝑤ℎ𝑒𝑟𝑒 𝑎, 𝑏, 𝑐, 𝑎𝑛𝑑 𝑑 𝑎𝑟𝑒 𝑖𝑛𝑡𝑒𝑔𝑒𝑟𝑠 𝑎𝑛𝑑 𝑏 𝑎𝑛𝑑 𝑑 ≠ 0, then we simplify the result by cancelling

denominators, factor both the numerator and denominator of the product, and cancel common

factors.

𝑝(𝑥) 𝑟(𝑥)

That is 𝑞(𝑥) . 𝑠(𝑥) =

𝑝(𝑥)𝑟(𝑥)

𝑞(𝑥)𝑠(𝑥)

, 𝑞(𝑥)...
