In this first section on algebra during year 9, we really want to get a good understanding of what we use letters for when doing mathematics, and why they are helpful. For now we will be mostly looking at expressions, which don’t show a relationship, but simply provide an efficient way of stating something.
We will break this topic down into the following 7 areas:
1.) Indices rules;
3.) Expanding brackets;
5.) Algebraic fractions;
6.) Substituting into expressions;
7.) Changing the subject of a formula.;
