Operasi jumlah Positif + positif = positif 4 + 6 = 10, 5 + 8 = 13, 7 + 9 = 16, dst. Negatif + negatif = negatif -4 +(-6)= -10, -5+(-8)= -13, -7+(-9) = -16, dst. Positif + negatif , pasangkan untuk membentuk nol, sisanya adalah hasil 4 + (-6) = [4 + (-4)] + (-2) = 0 + (-2) = -2 5 + (-8) = [5 + (-5)] + (-3) = 0 + (-3) = -3 7 + (-9) = [7 + (-7)] + (-2) = 0 + (-2) = -2 Negatif + positif, sama dengan cara positif + negatif -4 + 6 = [-4 + 4] + 2 = 0 +2=2 -8 + 5 = [5 + (-5)] + (-3) = 0 + (-3) = -3 -12 + 10 = [10 + (-10)] + (-2) = 0 + (-2) = -2 16
