# Martin Gardner's missing digits

Gwyn

Take a closer look at the # of digits in each line of the long-form solution.

When you decipher what duz is trying to type you get
(omitting the periods)

...........xxx8xx
.....__________
xxx.|.xxxxxxxx
..........xxx
..........----
...........xxxx
............xxx
.............---
.............xxxx
.............xxxx
..............----
.................0

Don't know how this will look but wanted to try..

Also my last answer should be it is the only result that is 8 digits long .(not 10)
Luz asked about a 7 in the quotient what would you do if their was an 8 in the quotient and 0 remainder
Can you help me out tried just adding 100 but it didn't come out, can you help me out.
the divisor is a xxx and the dividend is xxxxxxxx and 0 remainder, you guys are SUPER, tanks javier

Shouldn't there be five subtraction lines to get a 5 digit quotient?

ozo :
> Shouldn't there be five subtraction lines to get a 5 digit quotient?

not must,

1002-992 = 10 , and 100<124 therefor ZERO is automatically added to the quotient, and the subtruction is skipped,
this done 2 times => only 3 lines you see in the question.

jgb :

xxx = x1.x2.x3
xx8xx = x4.x5.8.x6.x7 , x5=x6 = 0
xxxxxxxx = abcdefgh

if you want to know how to solve this question without computer, start with the "8" :
the 2nd subtraction gives xxxx - xxx * 8 = xx, and in addition xx0 < xxx
=>
a) xxxx is 1xxx , and xxx is 9xx => a=1, x1=1
from here it is not copmicated at all to continuoue.
=> 1st and 2nd product are the same =>
3rd product is bigger (4 digits) => x7 > 8 => x7 = 9

from here every 6th class student can proceed alone.

Jgb3146,
...is this question addressed to me? I don't think we have met before , or have we? It looks like homework which should not be answered as per the site rules.
