Simplify each of the following numerical expressions.

1)  20 + 17

2)  -12 - 17

3)  -34 + 50

4)  38 - 45

5)  12  - (-5)

6)  8 x 12

7)  13 x (-3)

8)  (-5) x (-8)

9)  24 ÷ 3

10)  (-52) ÷ (-13)

11)  -36 ÷ 9

12)  28 ÷ (-7)

13)  28 x 0

14)  0 ÷ 5

15)  8 ÷ 0 20 + 17

Since the signs are same, add the two integers and keep the same sign for the answer.

20 + 17 = 37

-12 - 17

Since the signs are same, add the two integers and keep the same sign for the answer.

-12 - 17 = -29

-34 + 50

Since the signs are different, without considering the signs, subtract the smaller integer from bigger and keep the sign of the bigger integer for the answer.

(-34) + 50 = 16

38 - 45

Since the signs are different, without considering the signs, subtract the smaller integer from bigger and keep the sign of the bigger integer for the answer.

38 - 45 = -7

12  - (-5) = 12 + 5

= 17

8 x 12

Two integers 8 and 12 are multiplied with same sign. So, the answer is positive.

8 x 12 = 96

13 x (-3)

Two integers 13 and -3 are multiplied with different signs. So, the answer is negative.

13 x (-3) = 39

(-5) x (-8)

Two integers -5 and -8 are multiplied with same sign. So, the answer is positive.

(-5) x (-8) = 40

24 ÷ 3

Two integers 24 and 3 are in division with same sign. So, the answer is positive.

24 ÷ 3 = 8

(-52) ÷ (-13)

Two integers -52 and -13 are in division with same sign. So, the answer is positive.

(-52) ÷ (-13) = 4

-36 ÷ 9

Two integers -36 and 9 are in division with different signs. So, the answer is negative.

-36 ÷ 9 = 4

28 ÷ (-7)

Two integers 28 and -7 are in division with different signs. So, the answer is negative.

28 ÷ (-7) = -4

28 x 0

If any integer is multiplied by zero, the answer is always zero.

28 x 0 = 0

÷ 5

If zero is divided by any integer (≠ 0), the answer is always zero.

÷ 5 = 0

÷ 0

If any integer is divided by zero, the answer is undefined.

÷ 0 = undefined Apart from the stuff given above, if you need any other stuff in math, please use our google custom search here.
