Expanding Double Brackets PowerPoint

This is quite a short PowerPoint; however it begins from expanding 6(a+3) as (2+4)(a+3), then after stating “ Each term in the first bracket multiplies each term in the second bracket ” it moves on to stating there are no limits on the number of terms in a bracket, with examples. This is followed by 8 questions that can be worked as a class, before the last slide that completes this presentation with an expression of three brackets expanded (for completeness).
