(a)
384434 = 300000 + _____ + 400 + 34
384434 = 300000 + _____ + 434
384434 - 300000 - 434 = 84000
(b)
137167 = _____ + 30000 + 7000 + 100 + 60 + 7

137167 - 37167 = 100000
(c)
182543 = 100000 + 80000 + _____ + 500 + 40 + 3
182543 = 180000 + _____ + 543
182543 - 180000 - 543 = 2000
(d)
231321 = 200000 + 30000 + 1000 + _____ + 20 + 1
231321 = 231000 + _____ + 21
231321 - 231000 - 21 = 300
