Simplify: 30 divided by 5, plus 10 times (3 minus 2).
A60
B16
C12
D26
Answer & Solution
Correct answer: B. 16
1. Simplify inside the parentheses first: 3 minus 2 is 1.
2. There are no exponents, so do multiplication and division next, left to right: 30 divided by 5 is 6, and 10 times 1 is 10.
3. Finish with addition: 6 plus 10 equals 16.
4. Multiplying 6 by 10 instead of adding gives 60, the trap for skipping the final addition step.
