Solution of Lizzie's -

Yep - makes total sense now. Good old algebra - who said we'd never need it for anything useful?????

Lizziebith's link works on a similar principal.

any 2 digit number can be represented by the equation 10X+Y where X and Y are between 1 and 9.

So, the euqation this time is (10X+Y)-(X+Y). That equals 10X+Y-X-Y, which equals simply 9X. Since X can only be 1-9, the only possible solutions are 9, 18, 27, 36, 45, 54, 63, 72, and 81. So, like scaeagles said, they just seed those 9 numbers with the same symbol and voila, esp.

I am so impressed! Mind you I loved algebra, but it was not easy. I sweated blood for that A. And I've found it's like a foreign language; I lose it if I don't use it. Now, I DO understand those equations, but it would have taken me about a week to actually come up with them (if ever)!

Here's another one, similar to Lizzie's but the trick isn't based on mathematics. It's a clever one.

scaeagles I LIKE! Join Date: Jan 2005 Posts: 7,819	Solution of Lizzie's - Spoiler: There are only a certain number of answers that the solution can be. Go through it again, and notice the symbol of the number you select. When it refreshes for you to do again, look at the symbol next to the same number you had just arrived at. That will be the symbol displayed. The numbers that contain the only possible correct answers will always have the same symbol, and it will change every time, so that it looks like the program is predicting your answers.
