Question:

# $3(7^2 + 5) ÷ 6 – 3=$ _________.

A 24
explanation

Step 1: Find/Simplify Anything Involving Parentheses
Remember that $7^2$ really means (7 *7), which is 49.
$3(7^2+ 5) ÷ 6 – 3$
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
