Or, Just have some brain jelly....I've heard it's delicious!
Well, the symbols change every time you click to throw you off, but simply represent the relationship described in an equation and... It would appear that where x and y are real integers between 0 and 9 inclusive, (x * 10^1 + y * 10^0) - (x+y) = 9x, because, well, 9x = 9x. So, I guess they don't actually have to be integers or within any particular range, as this is a tautology. The only possible answers in the list from 0 to 99 are the multiples of nine: 0, 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, and 99 You'll always get a symbol next to one of these numbers, and the same symbol is always next to all of these numbers, but the particular symbol changes every round. If a person keeps guessing random numbers, they might never realize they were getting only multiples of nine, or that the symbols were constantly changing, as they'd likely keep jumping all over the list. but that's not quite right, is it? the highest number you could possibly get on the list is 99 - 18, o
