Unit 1 sec 2.2 Using your
calculator

You are expected to use
your calculator for most numerical calculations in MU123.
Sometimes you may find
that quicker to do a simple calculation in your head or on paper.
This is usually so that
you can practice a technique that you will need to use later when you do
Algebra.
When you type a
calculation into your calculator, it is important to think about the BIDMAS
rules, to ensure that the operations are carried out in the order you intended.
