Order of operations tells you to perform multiplication and division first working from left to right before doing addition and subtraction. Calculate 9 2 10 5 1 Solution. If we all agreed to do addition first then multiplication we would calculate and come up with 35 instead of 23.
The multiplication rule. We have agreed to. 30 5 6 leaving us with 6 x 2 1.

PtextA AND B PtextABPtextB The addition rule. Addition and Subtraction are also done in the same step. Additionally when was the order of operations created.
Expressions in parenthesis are treated as one number and must be calculated first. To make sense of the number sentence we can break it all down to addition. Example 2 What is 9 - 4 3.
