Answer:

29

Explanation:

7(4 + 5 + 2) - 6(3 + 5)

First we need to know what PEMDAS is. It is an acronym that helps remind you what steps to take when evaluating any kind of equation or expression.

  1. P-arentheses
  2. E-xponents
  3. M-ultiplication
  4. D-ivision
  5. A-ddition
  6. S-ubtraction

In PEMDAS, multiplication/division and addition/subtraction are in no particular order-- they are solved from left to right.

Knowing what PEMDAS means, you can start evaluating the expression. Start by solving inside the parentheses, as PEMDAS tells you to do.

Add 4 + 5 + 2 and 3 + 5 inside of the two parentheses in the expression.

7(11) - 6(8)

Since there are no exponents, you can skip this step and move on to multiplying 7 * 11 and 6 * 8.

(77) - (48)

The final process in evaluating this expression is to subtract 48 from 77.

29 is your answer.
