Question

Вычислить: 1) 6 + (- 7) 2) (- 5) + 14 3) (- 1) + 8 4) (- 20) + 13 5) (- 7) + 7 6) 9 + (- 14) 7) (– 8) + 11 8) 17 + (- 9) 9) (- 22) + 22 10) 8 + (- 13)

Answer 1

1) 6 + ( - 7 ) = 6 - 7 = - 1

2) ( - 5 ) + 14 = 14 - 5 = 9

3) ( - 1 ) + 8 = 8 - 1 = 7

4) ( - 20 ) + 13 = 13 - 20 = - 7

5) ( - 7 ) + 7 = 7 - 7 = 0

6) 9 + ( - 14 ) = 9 - 14 = - 5

7) ( - 8 ) + 11 = 11 - 8 = 3

8) 17 + ( - 9 ) = 17 - 9 = 8

9) ( - 22 ) + 22 = 22 - 22 = 0

10) 8 + ( - 13 ) = 8 - 13 = - 5

Answer 2

Ответ:

1. 6+(-7)= - 1

2. (-5)+14=9

3. (-1)+8= 7

4. (-20) +13= - 7

5. (-7)+7= 0

6. 9+(-14)= - 5

7. (-8)+11= 3

8. 17+(-9)=8

9. (-22)+22=0

10. 8+(-13)= - 7
