Apart — decompose into partial fractions with minimal denominators

Together — put rational functions over a common denominator

Cancel — cancel common factors between numerator and denominator

Numerator, Denominator — pick out numerator, denominator

PolynomialRemainder ▪ PolynomialQuotient

Factor — factor numerator and denominator, canceling common factors

Expand — expand everything except denominators

ExpandAll — expand everything, including denominators

ExpandNumerator, ExpandDenominator — expand numerators and denominators only

PadeApproximant — find a rational approximation to any function
