Description

Is it BIDMAS or BODMAS or something else?! Well, join me on an exploration of not only which is the correct way ... but how to use it! This video takes a look at how to use the order of operations to solve problems with, and without, the use of a calculator. We look at how Brackets, Indices, Division, Multiplication, Division, and Subtraction are used to solve problems. We look at how to use a simple four-function calculator and a CAS calculator to solve problems and how they come up with different answers. There are a number of worked examples and a chilled explanation on how to use both BIDMAS and BODMAS.
