Interesting. Wonder how that works with decimals.

Wow you look quite normal for a geek.

The statistics on sanity are that one out of every four persons is suffering from some sort of mental illness. Think of your three best friends -- if they're okay, then it's you.

Works in any base, since you're converting to unary in the process (i.e., each digit is how many lines you've drawn). Each grouping of intersections is a unary representation of the product of the respective digits, which came from their respective tens-place, and accordingly have to be grouped in diagonals and summed to get the same tens-place digit.

A more efficient representation, using lines, might be to use different line styles or coded positions to represent binary numbers. Their intersections then have to be multiplied, of course, but now you're doing single digit multiplications rather than N digits.

Answering questions is a tricky subject to practice. Not due to the difficulty of formulating or locating answers, but due to the human inability of asking the right questions; a skill that, were one to possess, would put them in the "answering" category.

This reminds me of Lattice multiplication and division. Which is practically the same things. Just one uses numbers and the other uses crossing points.
