What does BODMAS stand for and when do you use it?

BODMAS stands for Brackets, Order, Division, Multiplication, and Subtraction and tells you the order that operations should be performed in.

For instance in 2 x 5 + 3 - 6

Multiplication should be done first 2 x 5 = 10

10 + 3 - 6

Addition should be done next 10 + 3 = 13

13 - 6

Subtraction should be done last

so the answer is 7!

Typically in schools it is now taught as BIDMAS. Same principle, just swapping the O for I (Indices)
