Setting up Simple Expressions

This lesson to Setting up Expressions gives a good introduction to function machines and a variety of expressions and word problems but it still assumes that you already have a basic understanding of Order of Operations, Integer Multiplications and Simplifying Expressions. If you are not familiar with any of these topics I am linking our lessons here so that you can check them out before you start this lesson. Order of Operations:    • Order of Operations - BIDMAS, BEDMAS, BODMAS   Integer Multiplications:    • +/- Integer and Decimal Multiplication - N...   Simplifying Expressions:    • Simplifying Expressions - An Introduction ...   Vocabulary notes should be takend at 1:25 Try some Function Machine examples at 4:00 The uknown box contents example at 10:27 is similar to what we will see in the textbook. If you have already covered this topic and are fairly confident with all of the topics listed above, you may want to skip ahead to minute 13:38 where you can pause and practise before the answers are taken up at the end.
