Green Bridge Learning Resource For Algebraic Manipulation

Overview

Algebraic manipulation is the housekeeping of algebra: tidying expressions so they are as simple as possible. Collecting like terms, expanding brackets and factorising are the three core moves, and almost every later technique relies on doing them quickly and accurately.

In this lesson you will simplify expressions by collecting like terms, expand products of brackets, and factorise by taking out common factors. These skills are the toolkit for solving equations and working with formulas.
