To simplify an expression is to write it in a more efficient and compact form without affecting the value of the original expression.

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

Problem solving with expressions and equations

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

In this unit, pupils learn about generalisation and formal algebraic manipulation techniques such as substitution, collecting like terms and factorising.

Expressions and equations

In algebra, when we write the expression $$6(y-7)$$ as $$6y-42$$ it is called __________.

Without changing its value, we could write the expression $$5x+7+3x+8$$ more efficiently by {{ }} it.
