This first paragraph is mainly meant as a rehearsal of simplifying algebraic expressions. Something which is relatively new, but was already presented in chapter 6 in relation to calculating the area of right-angled polygons, is applying the order of operations to simplifying algebraic expressions. So video 1 will be dealing with this matter. In video 2 & 3 will be looked back on previous knowledge on simplifying multiplications, additions and subtractions of algebraic expressions.
- Video 1: Simplifying algebraic expressions & the order of operations
- Video 2: Multiplication & addition of like terms
- Video 3: Collecting like terms in complex mixes of additions & subtractions
