(a)
237509 = 200000 + _____ + 500 + 9
237509 = 200000 + _____ + 509
237509 - 200000 - 509 = 37000
(b)
618193 = _____ + 10000 + 8000 + 100 + 90 + 3
618193 = _____ + 18193
618193 - 18193 = 600000
(c)
264774 = 200000 + 60000 + _____ + 700 + 70 + 4
264774 = 260000 + _____ + 774
264774 - 260000 - 774 = 4000
(d)
436491 = 400000 + 30000 + 6000 + _____ + 90 + 1
436491 = 436000 + _____ + 91
436491 - 436000 - 91 = 400
