# Adding, subtracting, multiplying negative and positive numbers

Need help to verify if the answers are correct. I get really confused with this stuff. Sometimes I can't remember the correct sign to use(positive or negative). Please provide step by step instructions so that I am able to better understand how to solve the problems.

Find the sum:

1. -2 + (-3) = -5

2. 8 - 7 + = 5

3. 8 + (-5) = 3

4. 15 + (-3) = 12

5. -16 + 8 = -8

6. 7 + (-10) = 3

7. -9 + (-5) = -14

8. -12 +14 = 2

Find each difference.

9. 9 - 26 = 17

10. -4 - 15 = 19

11. 21 - (-7) = 28

12. 27 - (-16) = 43

13. -16 - (-43) = -59

14. 47 - 19 = 28

15. -156 - 98 = 254

16. -192 - 47 = 239

17. 0 - (-51) = -51

18. -63 - 89 = -23

19. -12 - (-21) = -33

20. 92 - (-16) = -76

Find each product or quotient.

21. -36/9 = -4

22, -52/-4 = +13

23. (-5) * (-20 ) = -100

24. -63/-9 = 7

25. (-15) * (2) = 30

26. 22/-2 = -11

27. (13) * (-6) = -78

28. -100/-5 = 20

29. (-60) * (-3) = 180

30. -240/30 = -8

31. (43) * (-8) = -344

32. -169/-13 = 13

Find the sum:

Some things to remember while adding positive and negative numbers --

a. Performing a sum on a positive number and a negative number is simply a subtraction where you subtract negative number from positive.

b. Performing a sum on 2 negative numbers is simply an addition of those 2 numbers and then putting a negative sign in front of them.

1. -2 + (-3) = -5 --> Use the principle (b) from above. (add negative numbers and just put a - in front)

2. 8 - 7 + = 5 --> Is this 8 - 7 or what ? Please message me, and I'll let you know the answer.

3. 8 + (-5) = 3 --> Use the principle (a) from above. (subtract negative number from positive 8 - 5 )

4. 15 + ...
