1. b.    Perform the operations within the parentheses first: 15 + 32 = 47; 56 –39 = 17. Then, multiply those sums as indicated by the adjoined parentheses: 47 × 17 = 799.
2. a.   The correct answer to this division problem is 9.
3. d.   The correct answer to this multiplication problem is 25,200.
4. c.   The correct answer to this multiplication problem is 15,050.
5. a.   The correct answer to this multiplication problem is 7,290.
6. d.   56,515 ÷ 4 = 14128.75, or, rounded to the nearest whole number, 14,129.
7. d.   The bars on either side of –9 indicate "the absolute value of –9." The absolute value of a number is the distance that number is away from zero on a number line. The absolute value of –9 is 9 because it is nine units away from zero. Because absolute value is a distance, it is always positive.
8. b.   Perform the operation within the parentheses first: 6 + 3 = 9; then, multiply the sum by 5. The correct answer is 45.
9. a.   The correct answer is 15. An incorrect answer may represent an error in place value.
10. c.   The correct answer is 12,407. If you chose choice a, you disregarded the zero in 62,035.
11. c.   The answer when the two numbers are divided is approximately 100.03, which is closest to 100. The question can also be evaluated using compatible numbers, such as 6,300 ÷ 63; and the solution here is also 100.
12. a.   The correct answer is 205,335.
13. a.   Perform the operations in parentheses first: 84 –5 = 79 from the first set and 3 × 54 = 162 from the second set. The expression is now 12(79) –162.Multiply 12 times 79 to get 948, and then subtract: 948 –162 = 786.
14. b.   The correct answer to this multiplication problem is 250,608.
15. d.   Perform the operation within the parentheses first: 12 × 6 = 72; then, add the product by 18. The correct answer is 90.
