Week 9 Math: Order of Operations

1

In this problem, following order of operations, I would divide 2 by 2 before I add 36.  This would leave me with an answer of 37.

But if I add parentheses around 36 + 2 then that changes the answer.

First I add 36 and 2 and get 38, then I divide by 2 to get 19.  Different answer because of where I placed my parentheses.

In the following three problems add parentheses to the problem to change the answer.

1

Add parentheses to the equation so the answer is 7.

1

Add parentheses to the equation so the answer is 18.

1

Add two sets of parentheses to the equation so the answer is 2.

1

(91-6×7)+2-6

Show step by step how you solved problem number six.

1

5+8+(5+3)+18÷9

Put these steps in order from first to last.

When using order of operations, you always work from left to right if you have mutliple of the same type or level of operation.
