Simplify: 18 divided by 6, plus 4 times (5 minus 2).
AEquals 9
BEquals 24
CEquals 15
DEquals 6
Answer & Solution
Correct answer: C. Equals 15
1. Simplify inside the parentheses first: 5 minus 2 is 3.
2. There are no exponents to simplify next.
3. Multiplication and division come next, working left to right: 18 divided by 6 is 3, and 4 times 3 is 12.
4. Finish with addition: 3 plus 12 equals 15.
5. Adding 6 and 4 before finishing the multiplication and division would wrongly break the left to right rule.
