Answer:

325

Explanation:

Writing out the equation always makes it easier to solve:

( 21 / 7 ) + 7 + 7( 7 - 2 ) x 9

First, following the rules of P.E.M.D.A.S.

(parenthesis, exponents, multiplication, division, addition, subtraction.)

You would need to solve for the values within each parenthesis... so

(21 / 7). 21 divided by 7 is equal to 3. And in (7 - 2). 7 minus 2 is equal to 5.

The equation is now:

( 3 ) + 7 + 7( 5 ) x 9

Next you must solve for multiplication, so:

7( 5 ), 7 times 5 is 35. the equation is now:

( 3 ) + 7 + ( 35 ) x 9

Then, 35 x 9 is equal to 315. The equation is now:

( 3 ) + 7 + 315.

If you add everything together, you get the answer of:

325!!!
