Algebraic representation and manipulation
In the 60th minute the trainer decides to replace a player for another. After the game the trainer will evaluate how the substitution affected the outcome of the match. As a mathematician, you do the same when you substitute a value into an algebraic expression and evaluate its outcome. Follow the links below and find out how practical algebra really is! I will explain to you how to manipulate algebraic expressions and equations. You will need these skills to answer many questions on your maths exam. First I will show you the important language which you need to be familiar with (otherwise you do not understand what you are asked to do). Then I will explain to you how to simplify expressions and how to combine like terms. Thirdly I will show you how to get rid of brackets and expand expressions. Hereafter I will show you the exact opposite and explain how to factorise different types of expressions. Then I will explain to you how to evaluate expressions by substitution. The sixth section will be about the transformation of formulae. I will explain to you how you can change the subject of an equation/formula. Finally we will work with algebraic fractions. I will explain to you how to simplify algebraic fractions and how you can combine them. As you can see we have a lot of work to do. So don't waste your time and start your maths revision now! by clicking on the first link! I will see you there!!
