Every number you use in Mathematics sits somewhere in the real number system, and knowing where it sits tells you how it behaves.
About 4 minExpanding multiplies brackets out; factorising puts them back. Recognising standard forms saves you enormous time.
About 3 minAlgebraic fractions follow the same rules as numeric fractions — but you must factorise before you simplify.
About 3 minExponent laws let you simplify powerful-looking expressions quickly, and they underpin scientific notation and growth formulae.
