An equation is used to show that one number or calculation is equal to another.

An exponent is a number positioned above and to the right of a base value. It indicates repeated multiplication.

An operation is commutative if the values it is operating on can be written in either order without changing the calculation.

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.
