I was always very good at doing multiplication in my head. With three digit numbers I could multiply them in my head almost as fast as the person could say them. My mind just had a gift for numbers. But what was odd was that geography was the same way for me, I could remember places and names, but for the life of me I couldn't remember faces and names at all. My mind would draw a complete blank.My roomate in college and I competed one week in doing 3 and 4 digit multiplications in our heads, who could get the right answer first. (neither of us were savants or such, so it was a mental effort thing, who was more determined

Nowadays anything beyond two digit numbers and I'm looking for a calculator, and I still can't remember faces and names. But that's perfectly fine with me. I like getting old. I like forgetting, it makes me feel normal.
Too many frogs.Maybe it was a failure of Egyptian mathematics which led to a massive architectural failure in the form of the Bent Pyramid.
The pharaoh eventually got it right (third time lucky).![]()

I never, ever would've thought of doing it the way the first guy did. That was impressive. Why he did it that way I don't know, because the way the second guy did it was fairly obvious. The first question that I asked myself was, how do I get that "1" at the end? And there seem to be just two likely scenarios, get to 815 and add six, or get to 825 and subtract 4. A quick look at the numbers suggests that getting to 815 just isn't gonna happen. Then it's just a matter of figuring out how to get to 825, and it's almost like you can't help but get 825. You can do (100+25)*6=750, then add 75 and you're at 825. Or you can go (75+50)*6=750 then add 100, then subtract 25 and you're at 825. Or you can go (100+50)*6=900, then subtract 75 and again you're at 825. So the way the second guy did it seems so simple that it's hard to fathom why the first guy did it the hard way.I find this very impressive.

This is Snefru's cartouche.The Bent Pyramid is sometimes referred to as King Snafu's tomb.

Who invented the one that falls off all the time?They invented the second hand on a clock

The bent pyramid successfully stores more grain.Maybe it was a failure of Egyptian mathematics which led to a massive architectural failure in the form of the Bent Pyramid.

I much prefer the hypothesis the pyramids were built by aliens.The bent pyramid successfully stores more grain.

Are you familiar with Fabricius, Googles AI algorithm for translating Egyptian hieroglyphs?
I tried it on Khufu's cartouche but wasn't successful.
