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. ;) |

Re: Math Help
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. |
Dang it, I should stop watching TV when doing math... :lol: I got beat.
