Answer 1

Explicação passo-a-passo:

(+38) + ( -9) = 29

(+97) + (+98) = 195

( -81) + ( -96) = -177

( -75) + (+1) = -74

( -57) + ( -61) = -118

( -7) + (+78) = 71

(+8) + (+60) = 68

(+72) + (+22) = 94

(+74) + (+99) = 173

(+59) + ( -5) = 55

( -64) + (+8) = -56

(+48) + ( -78) = -30

(+84) + ( -2) = 82

( -3) + ( -51) = -54

(+73) + ( -54) = 20

( -52) + (+35) = -17

( -2) + ( -35) = -37

( -12) + ( -91) = -103

(+62) + (+33) = 95

( -94) + (+55) = -39

( -33) + (+22) = -11

( -28) + ( -94) = -122

( -1) + (+23) = 22

(-30) + (+30)= 0

(-60) + (+60) = 0

( +85) + (-85) = 0
