- ; - = -

+ ; - = -

Sólo es cuestión de aplicar ley de signos y usas el signo del mayor.

(-5)+(+9)=(-5)+9= +4

(-3)+(-6)= (-3) - 6= -9

(-9)+(+3)= (-9) + 3 = -6

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

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

(-7)-(-4)= (-7) + 4 = -3

(-7)+(+6)= (-7) + 6 = -1

(-6)+(-5)= (-6) - 5 = -11

(-5)+(+5)= (-5) + 5 = 0

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