Does anyone know how you should solve this math problem? The question marks are the numbers you have to find the value to.. I'm totally stumped and someone asked me to help them out and I have no clue. lol

You weren't suppose to ask that :lol:
Just by looking it was easy to see the last digit of the first number would be 1. That got us down to needing 2 digits or 99 possibilites. I got stuck there and just made a spread sheet that multiplied 1001 - 1999 x 417 and looked for the answer. In other words - I cheated. ;)

You just set it up like a normal multipication problem
_1???
_x417
xxxxx
xxxx0
xxx00
???57

Then you know that top right ? has to be a 1 to make ???57 then keeping goin you know:
_1??1
_x417
xxxx7
xxx10
xxx00
???57

Then that secnod ? from the top right has to be a 2 the make the 4+1=5 in the answer:

_1?21
_x417
xxx47
xxx10
xxx00
???57

And you just keep goin

1??1
X 417
-----------
7x47
1xx10
4xx400
------------
???057

So, we know 7x47, so we get 1?21, and then 1x210



1?21
X 417
-----------
x7x47
x1x210
4xx400
------------
???057

So, 10-4-2=4, then we have 7447, that makes 1921,

1921
X 417
-----------
x7x47
x1x210
4xx400
------------
???057

Then just do the math to fill in the rest of the x's and ?'s.
