At first I was thinking adding before subtracting but then I realised it was meant to be dividing before multiplying instead

But yeah it makes sense now :smile:

Great. I thought there was a possibility that you thought BIDMAS means you do addition before subtraction which is a common confusion.

That isn't the rule here. The fact that there are 2 multiplications and 1 division is a consequence of the 2 additions and 1 subtraction in the original expression.
