For example, in the expression \(3(m + 7)\), multiply both \(m\) and 7 by 3, so: \(3(m + 7) = 3 \times m + 3 \times 7 = 3m + 21\). Expanding brackets involves using the skills of simplifying algebra.

Revise how to simplify algebra using skills of expanding brackets and factorising expressions with this BBC Bitesize GCSE Maths Edexcel guide.

It reads now, "A placeholder for a mathematical expression (for example: x^2-3x=0) ... You can then "solve" the math expression, which may involve simplifying, transforming, ...
