(a)
580771 = 500000 + _____ + 700 + 71
580771 = 500000 + _____ + 771
580771 - 500000 - 771 = 80000
(b)
498239 = _____ + 90000 + 8000 + 200 + 30 + 9

498239 - 98239 = 400000
(c)
122219 = 100000 + 20000 + _____ + 200 + 10 + 9
122219 = 120000 + _____ + 219
122219 - 120000 - 219 = 2000
(d)
281112 = 200000 + 80000 + 1000 + _____ + 10 + 2
281112 = 281000 + _____ + 12
281112 - 281000 - 12 = 100
