- C. 31.49
- D. 32.29
- E. 32.49
Show Answer
Line up the decimal points and add:
5.68 + 3.40 + 19.21 + 4.00 = 32.29
- A. 0
- B. 50.49
- C. 162
- D. 280.5
- E. 704.7
Show Answer
The expression contains a factor of 0.
Any product containing 0 equals 0, so the entire expression equals 0.
- A. −27
- B. −7
- C. −1
- D. 1
- E. 19
Show Answer
Add from left to right:
−4 + (−13) = −17
−17 + 10 = −7
- A. −61
- B. −15
- C. 13
- D. 15
- E. 61
Show Answer
Subtracting a negative number is equivalent to adding the corresponding positive number:
23 − (−38) = 23 + 38 = 61
- A. 4
- B. 5
- C. 6
- D. 7
- E. 8
Show Answer
Evaluate the expressions inside parentheses first:
20 ÷ 5 = 4
12 ÷ 4 = 3
Then add:
4 + 3 = 7
- A. 656
- B. 655
- C. 755
- D. 756
- E. 765
Show Answer
Group numbers that are convenient to add:
215 + 490 = 705
56 + 4 = 60
705 + 60 = 765
- A. −30
- B. −20
- C. 18
- D. 20
- E. 30
Show Answer
A positive number divided by a negative number produces a negative quotient.
780 ÷ 26 = 30
Therefore:
780 ÷ (−26) = −30
- A. −132
- B. −66
- C. 66
- D. 96
- E. 132
Show Answer
Evaluate each expression inside parentheses:
4 + 7 = 11
9 − 3 = 6
Then multiply:
11 × 6 = 66
- A. −240
- B. −120
- C. −80
- D. 80
- E. 120
Show Answer
Multiply from left to right:
3 × (−5) = −15
−15 × 8 = −120
−120 × 2 = −240
The product is negative because the expression contains one negative factor.
- A. 1.911
- B. 1.981
- C. 2.181
- D. 2.171
- E. 2.709
Show Answer
Write 4.81 as 4.810 so the decimal places line up:
6.791 − 4.810 = 1.981
How to Use These Questions
Work each expression before opening the explanation. Write intermediate steps when the problem contains several operations, negative values, or decimals.
For decimal addition and subtraction, line up the decimal points. For signed multiplication and division, determine the sign of the answer before calculating its magnitude.
