Like terms are terms that have the same set of variables and corresponding exponents.

Simplifying is to write an expression in the most efficient and compact form without affecting the value of the original expression.

Simplifying by collecting like terms

Maths

In this unit, pupils formalise algebraic notation and terms and begin to formulate an understanding of basic algebraic manipulation. This understanding is built upon in the future unit where pupils learn how to solve linear equations

In this unit, pupils learnt how to represent the structure of a problem with two unknowns using a diagram. This understanding is built upon in this unit and formalised
