Question

Determine as somas:
b)(+3)+(-7) + (-2) + (+10)
a)
(-9) + (+11) + (+6)
d) (-8) + (+7) + (+10)+(-9)
h) (-5) + (-8) + (+1)+(+6)​

Answer 1

Resposta:

a)= 8

b)= 4

h) = -6

d) =0

Explicação passo-a-passo:

b) (+3)+(-7)+(-2)+(+10)

=3-7-2+10

= -4-2+10

= -6+10

= 4

a) (-9)+(+11)+(+6)

= -9+11+6

= 2+6

= 8

d) (-8)+(+7)+(+10)+(-9)

= -8+7+10-9

= -1+10-9

= 9-9

= 0

h) (-5)+(-8)+(+1)+(+6)

= -5-8+1+6

= - 13+1+6

= -12+6

= -6
