❖ 6 + 45 ÷ 3² = 11
Follow order of operations:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
(Note: Multiplication and division can be done in either order as well as addition and subtraction.)
There are no parenthesis in this problem so we skip to exponents. The exponent is 3² which is 3 x 3 = 9.
We then have division. 45 ÷ 9 = 5
Our last step is addition.
Add:
6 + 5 = 11

- Explantion: 360 °/ 12 = 30 <span>°</span>
2 + 3 = 5 Add whole numbers
10/12 + 3/12 = 13/12
13/12 = 1 and 1/12
5 + 1 = 6
6 + 1/12 = 6 and 1/12
Answer: 6 and 1/12
