Question

solve the problem & show work. circle your final answer - be careful of signs & operations

1. 15 ÷ -3
2. (-7) * (-7)
3. (5)(10)
4. | -6 | ÷ 2
5. -3/27
6. | -5 | | -4 | | -4 |
7. -560 ÷ 7
8. (-1)(-8)(12)

Explanation:

Step1: Solve 18)

Divide 15 by - 3. A positive number divided by a negative number gives a negative result.
$15\div(-3)=- 5$

Step2: Solve 19)

Multiply - 7 by - 7. A negative number multiplied by a negative number gives a positive result.
$(-7)\times(-7)=49$

Step3: Solve 20)

Multiply 5 by 10.
$(5)(10)=50$

Step4: Solve 21)

First, find the absolute - value of - 6, which is 6. Then divide 6 by 2.
$|-6|\div2 = 6\div2=3$

Step5: Solve 22)

The fraction $\frac{27}{-3}$ is equivalent to $27\div(-3)$. A positive number divided by a negative number gives a negative result.
$\frac{27}{-3}=-9$

Step6: Solve 23)

First, find the absolute - values: $|-5| = 5$, $|-4| = 4$, $|-4| = 4$. Then multiply them together.
$|-5|\times|-4|\times|-4|=5\times4\times4 = 80$

Step7: Solve 24)

Divide - 560 by 7. A negative number divided by a positive number gives a negative result.
$-560\div7=-80$

Step8: Solve 25)

First, calculate $(-1)(-8)=8$ (negative times negative is positive), then multiply 8 by 12.
$(-1)(-8)(12)=8\times12 = 96$

Answer:

1. - 5
2. 49
3. 50
4. 3
5. - 9
6. 80
7. - 80
8. 96
