OK, so far "Robbie" has only done one piece of math to the input numbers.

We are now going to reprogram "Robbie" to do TWO pieces of math to them.He is going to give us a hint though: he is going to do a multiply and then an add. Again it is the same rule each time.

Now it is your turn to be "Robbie".

Think of some input numbers and do TWO pieces of math to them and write down the answers.

Everyone else is going to try to work out what the rule is!

To make it a bit harder you can chose numbers that are not in order.
