Answer:

Step 1: Find/Simplify Anything Involving Parentheses

Remember that 72 really means 7×7–––––, which is 49.

3(72––+5)÷6−3

Is now …

3(49+5)÷6−3

Since there is still an expression in parentheses, we add the two numbers in parentheses. 

3(49+5––––––)÷6–3

Which is now …

3(54)÷6−3

Step 2: Once Parentheses Are Complete, Move On

Since there are no more operations in parentheses and no more exponents, we now move on to multiplication and division – whichever comes first working from left to right. 

3(54)–––––÷6–3

Becomes: 

162÷6−3

We then perform the division.

162÷6––––––––−3

And get: 

27−3

Step 3: Continue Following Order of Operations

Since we only have one operation left, we can solve it.

27–3=24
