Answer 1

Respuesta:

a) -23 + (+45)

= -23 + 45

= 22

_______________________________

b) -28 + (+28)

= -28 + 28

= 0

_______________________________

c) -20 + (-2) + (-6)

= -22 + (-6)

= -22 -6

= -28

_______________________________

d) 11 - (+3) - (+5)

= 11 - 3 - 5

= 11 - 8

= 3

_______________________________

e) - (+25) + (-4) - (+40)

= -25 - 4 - 40

= -29 - 40

= -69

_______________________________

f) -12 +3 - {8 - 19 + 4  - 1 +(-2+ 8)] + 3)

= -12 +3 - {8 - 19 + 4  - 1 + 6] + 3)

= -12 +3 - {-11 + 4  - 1 + 6] + 3)

= -12 +3 - {-7  - 1 + 6] + 3)

= -12 +3 - {-8 + 6] + 3)

= -12 +3 - {-2] + 3)

= -12 +3 - {1)

= -9 - {1)

= -10

g) 2- (1 - 2) - {-2-15 - (5 - 13)] + 6)

= 2- (-1) - {-2-15 - (-8)] + 6)

= 2- (-1) - {-17 - (-8)] + 6)

= 2- (-1) - {-17 + 8] + 6)

= 2- (-1) - {-9] + 6)

= 2 + 1 - {-9] + 6)

= 2 + 1 - {-3)

= 2 + 1 + 3

= 3 + 3

= 6

= - {25) - 3+ [0)

= - {22+ [0)

= - {22}

= -22
