I'm talking about doing it in your head. 11 X 4334. So, with the other method, it would be 43340 + 4334. Not exactly the fastest way, unless you are really good at adding and keeping the numbers still in your head. But, with me method, it would be 4_ _ _4, some quick adding, 3+4, 3+3, 4+3, and that's 47674. Alot faster, I think.
Turn what you just did sideways.

Sure, it's an artifact of base 10

More my fault for having a algebra textbook that obsessed with abnormal base calculations

Your method for 11 might be even quicker!

That is wayyyyy more complicated than 10x+x. But if it works for you, I am happy. *NM*
