BIDMAS (also known as BODMAS) helps you to remember the order that you need to do your mathematical calculations where there is more than one mathematical operator (any combination of brackets, indices, division, multiplication, addition, subtraction).

This easily remembered acronym stands for:

B rackets
I ndices (powers of)
D ivision
M ultiplication
A ddition
S ubtraction

Take a look at the video (below) in which Dee Greig-Dunn, Lecturer in Mathematics and Meteorology at Solent University, explains how to apply BIDMAS (BODMAS)  to the following calculation:

(3 + 4)² - 7 + 4 × 3

Remember: numbers showing as ¹ or ² or ³ are know as Indices (or powers)
