705 = (60 + 10) − 5 = 60 + (105) = 60 + 5 = 65
804 = (70 + 10) − 4 = 70 + (104) = 70 + 6 = 76
1004 = (90 + 10) − 4 = 90 + (104) = 90 + 6 = 96
1009 = (90 + 10) − 9 = 90 + (106) = 90 + 1 = 91
52 + 8 = (50 + 2) + 8 = 50 + (2 + 8) = 50 + 10 = 60
608 = (50 + 10) − 8 = 50 + (108) = 50 + 2 = 52
4320 = (40 + 3) − 20 = 3 + (4020) = 3 + 20 = 23
432 = (40 + 3) − 2 = 40 + (32) = 40 + 1 = 41
