Answer 1

Respuesta:

-8

-4

17

Explicación paso a paso:

Answer 2

Resuelve :

¹⁴⁵· (+5)-(-6) = -1

¹⁴⁶. (+5)-(+6) = -1

¹⁴⁷. (-5)-(-6) = -11

¹⁴⁸. (-5)-(+6) = -11

¹⁴⁹. (-3)-(+9) = -12

¹⁵⁰. (-3)-(-9) = 6

¹⁵¹. (+3)-(+9) = -6

¹⁵². (+3)-(-9) = 12

Realiza las operaciones:

¹⁵³. (+8)-(+9)+(-7)

-1 + (-7)

= -8

¹⁵⁴. (-12)-(-3)+(+5)

-9 + (+5)

= -4

¹⁵⁵. (+9)+(-13)-(-21)

-4 - (-21)

= 17

¹⁵⁶. (-17)+(+5)-(+20)

-12 - (+20)

= -32

¹⁵⁷. (-7)-(-12)-(+3)

5 - (+3)

= 8

Calcula :

¹⁵⁸. (-5)-(+11)-(-20)

-16 - (-20)

= -36

¹⁵⁹. 9-[(-5)-(+7)]

9 - (-12)

= -21

¹⁶⁰. -7-[(-3)-(-9)]

-7 - 6

= 1

¹⁶¹. (-11)-[(+6)-(+4)]

-11 - 2

= -13

¹⁶². +8-[(+5)-(-9)]

+8 - 14

= -6

¹⁶³. (+4)+[(+3)+(-7)]+(+1)

(+4) + (-4) + (+1)

0 + (+1)

= 1
