Answer 1

Step-by-step explanation:

Perform the following operations on Integers :-

1. (+5) + (+2) 6. (-7) + (-3) 11. (+9) + (-4)

2. (-5) + (-2) 7. (+7) + (-3) 12. (-9) + (+4)

3. (+5) + (-2) 8. (-7) + (+3) 13. (-7) +(-2)

4. (-5) + (+2) 9. (+9) + (+4) 14. (-7) +(+2)

5. (+7) + (+3) 10. (-9) + (-4) 15. (+7) +(-2)

II. Perform the following operations on Integers :-

1. (+5) - (+2) 6. (-7) - (-3) 11. (+9) - (-4)

2. (-5) - (-2) 7. (+7) - (-3) 12. (-9) - (+4)

3. (+5) - (-2) 8. (-7) - (+3) 13. (-7) - (-2)

4. (-5) - (+2) 9. (+9) - (+4) 14. (-7) - (+2)

5. (+7) - (+3) 10. (-9) - (-4) 15. (+7) -(-2)

III. Perform the following operations on Integers :-

2. (-5) X (-2) 12. (-9) X (+4)

3. (+5) X (-2) 13. (-7) X(-2)

4. (-5) X (+2) 14. (-7) X (+2)

5. (+7) X (+3) 15. (+7) X (-2)

6. (-7) X (-3) 16 . -8 / -2

7. (+7) X (-3) 17. -8/2

8. (-7) X (+3) 18. 8/(-2)

9. (+9) X (+4) 19. 24/(-2)

10. (-9) X (-4) 20. -18/6

IV. Find (a) (-7)-8-(-25) (b) (-13) + 32-8-1 (c) (-7) + (-8) + (-90) (d) 50-(-40)-(-2)
