Answer 1

Explicação passo-a-passo:

$(a) (+3) -(+5)-(-10)= \\ - 2 - ( - 10) = \\ 8$

$(b) (+2)+(-6)-(+5)+(2)= \\ - 4 - 7 = \\ - 3$

$(c) (-5)-(-8)+(-7)-(-9)+(-3)= \\ 3 + ( - 7) - ( - 12) = \\ 3 + 5 = \\ 8$

$(d) (-2)-(-4)-(+7)-(-2)+(-12)= \\ 2 - 9 + ( - 12) = \\ 2 - ( - 3) = \\ 5$

$a)+8+7=15$

$b)9+3=12$

$c)-10+5= - 5$

$d)-2-8= - 10$

$e)-9-12= - 21$

$f)-8+8=0$

$a)-6+8+6-4+4+1= \\ 2 + 2 + 5 = \\ 4 + 5 = \\ 9$

$b)4-9+2-1+9-2 = \\ - 5 + 1 + 7 = \\ - 4 + 7 = \\ 3$

$c)5+6-7+1+7-10= \\ 11 - 6 - 3 = \\ 5 - 3 = \\ 2$

$d)12-6+5-5+6-12= \\ 6 + 0 - 6 = \\ 0$
