Unit 4: Math in Real World
If you have not completed Units 2 and 3 yet, it is recommended that you go back and finish those sections first.
In this unit we will take a look at exponents (which follows on from multiplication) and the importance of carrying out calculations in the correct order when faced with a problem with several different operators involved, for example addition and division. Finally we will turn to a method of solving problems and how this can be used in our everyday lives.
To check your understanding of exponents and PEMDAS before you start, do the Unit 4 pre quiz, then use the feedback to help you plan your study.
The quiz checks most of the topics in the unit, and should give you a good idea of the areas you may need to spend most time on. Remember, it doesn’t matter if you get some or even all of the questions wrong—it just indicates how much time you may need for this unit!
