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.

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

When an expression cannot be simplified further, we say it has been {{ }} simplified. 

Fully simplify the expression $$2x+3y+7x-y$$

Which of the below statements is true of the expression $$9x+2y$$?

Which of these best describes what is expressed by this set of algebra tiles?
