(a)
883193 = 800000 + _____ + 100 + 93
883193 = 800000 + _____ + 193
883193 - 800000 - 193 = 83000
(b)
771715 = _____ + 70000 + 1000 + 700 + 10 + 5

771715 - 71715 = 700000
(c)
673124 = 600000 + 70000 + _____ + 100 + 20 + 4
673124 = 670000 + _____ + 124
673124 - 670000 - 124 = 3000
(d)
935452 = 900000 + 30000 + 5000 + _____ + 50 + 2
