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.
