1. Answer :

-3 + 8

First number is -3 ----> start at -3.

A positive number 8 is added ----> move 8 units to the right of -3.

So, -3 + 8 = 5.

2. Answer :

4 + (-2)

First number is 4 ----> start at 4.

A negative number -2 is added ----> move 2 units to the left of 4.

So, 4 + (-2) = 2.

3. Answer :

-8 + 5

First number is -8 ----> start at -8.

A positive number 5 is added ----> move 5 units to the right of -8.

So, -8 + 5 = -3.

4. Answer :

-1 + (-3)

First number is -1 ----> start at -1.

A negative number -3 is added ----> move 3 units to the left of -1.

So, -1 + (-3) = -4.

5. Answer :

5 - 7

First number is 5 ----> start at 5.

A positive number 7 is subtracted ----> move 7 units to the left of 5.

So, 5 - 7 = -2.

6. Answer :

4 - (-2)

First number is 4 ----> start at 4.

A negative number -2 is subtracted ----> move 2 units to the right of 4.

So, 4 - (-2) = 6.

7. Answer :

-2 - 3

First number is -2 ----> start at -2.

A positive number 3 is subtracted ----> move 3 units to the left of -2.

So, -2 - 3 = -5.

8. Answer :

-5 - (-3)

First number is -5 ----> start at -5.

A negative number -3 is subtracted ----> move 3 units to the right of -5.

So, -5 - (-3) = -2.

9. Answer :

5 x (-7)

5 times 7 is equal to 35.

Since a positive number is multiplied by a negative number, the answer is negative.

So, 5 x (-7) = -35.

10. Answer :

(-4) x 9

4 times 9 is equal to 36.

Since a negative number is multiplied by a positive number, the answer is negative.

So, (-4) x 9 = -36.

11. Answer :

(-3) x (-6)

3 times 6 is equal to 18.

Since a negative number is multiplied by a negative number, the answer is positive.

So, (-3) x (-6) = 18.

12. Answer :

15 ÷ (-3)

15 divided by 3 is equal to 5.

Since a positive number is divided by a negative number, the answer is negative.

So, 15 ÷ (-3) = -5.

13. Answer :

(-20) ÷ 5

20 divided by 5 is equal to 4.

Since a negative number is divided by a positive number, the answer is negative.

So, (-20) ÷ 5 = -4.

14. Answer :

(-28) ÷ (-4)

28 divided by 4 is equal to 7.

Since a negative number is divided by a negative number, the answer is positive.

So, (-28) ÷ (-4) = 7.
