The order of operations - 3rd grade math (addition, subtraction, parenthesis only)

Описание к видео The order of operations - 3rd grade math (addition, subtraction, parenthesis only)

In this lesson, we learn about parenthesis and how they affect the order in which we do additions and subtractions. Normally, if there are several additions and subtractions, you do them from left to right. But with parenthesis you can change that.

In these examples, I draw a bubble or a "balloon" around the operation to be done first - makes math easier and colourful!
