9999 + 9 = 10008
999/9 = 100
9999 ÷ 10 = 999.9 Or 999 remainder 9
dcba = 9 x abcd dcba/9 = abcd Since the quotient is also a 4 digit number, then d in order to be divided by 9, must be the biggest digit which is 9. So that d = 9 and a = 1. The same way for other digits... So that we have: dcba = 9 x abcd 9999 = 9 x 1111
9999 = 9999 It does NOT equal '1' 1 = 1 9999 ~ 10,000 (ten thousand)
