Answer:
29
Step-by-step 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.
- P-arentheses
- E-xponents
- M-ultiplication
- D-ivision
- A-ddition
- 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.
