Answer 1

Respuesta:

1. = 5

2. = 11

3. = 17

4. = -80

5. = 1

6. = 20

7. = 13

8. = 15

9. = 9

10. = 12

Explicación paso a paso:

1. -45:(-27:3)

-45:(-9)

= 5

2. 7 + 2.2

7+4

= 11

3. 7 + 3 - (-7)

10+7

= 17

4. 10. (-48:6)

10.(-8)

= -80

5. 1. (-2) + 3

-2+3

=1

6. (-4:2).(-10)

-2.(-10)

= 20

7. 7-3.(-2)

7-(-6)

= 13

8. 14-6+7

8+7

= 15

9. 27:(24:8)

27:3

= 9

10. 1-(-9)-(-2)

10+2

= 12
