A term is single number or letter, or the product of numbers and/or variables. Each term is separated by the operators + and –

An expression contains one or more terms where each term is separated by an operator.

Simplifying before multiplying with multiple expressions

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
