Question

Calcule as operações com números inteiros: (+8) + ( - 5) = ( - 12) + ( + 20)= ( + 3) + ( + 14)= ( - 2) + ( - 10)= (+8) - ( - 5) = ( - 12) - ( + 20)= ( + 3) - ( + 14)= ( - 2) - ( - 10)= (+8) . ( - 5) = ( - 12) . ( + 20)= ( + 3) . ( + 14)= ( - 2) . ( - 10)= (+10) : ( - 5) = ( - 24) : ( + 2)= ( + 36) : ( + 12)= ( - 2) : ( - 1)= pfv com conta

Answer 1

(+8) + (-5) = +8-5= +3

(-12)+(+20) = -12 +20 = +8

(+3) +(+14) = +3+14 = +17

(-2) +(-10)= -2 -10 = -12

(+8) -(-5) = +8 +5 = +13

(-12) - (+20) = -12 -20 = -32

(+3) -(+14) = +3 -14 = -11

(-2) -(-10) = -2+10 = +8

(+8). (-5) = -40

(-12). (+20) = - 240

(+3). (+14) = + 42

(-2).(-10)= +20

(+10): (-5) = -2

(-24): (+2) = -12

(+36) : (+12) = + 3

(-2): (-1) =+1

bons estudos!
