## Order of Operations Part 2 – Concept [Video – 10:08] (2011)

This short video tutorial deals with the concept of order of operations in mathematics problems and builds on the material covered in earlier lessons.

The narrator reviews the concept, explaining that when a problem contains some combination of addition, subtraction, multiplication or division, the order of operations specifies that the multiplication and division components must be completed first, before carrying out the addition and subtraction work.

He then explains that when the problem contains calculations contained within brackets, the bracketed calculations must be completed first.

The tutorial introduces the mnemonic BEDMAS, which stands for Brackets, Exponents, Division, Multiplication, Addition, and Subtraction, although the instructor points out that exponents will be dealt with only in higher mathematics.

The tutorial also touches on calculations involving negative numbers.
