Así se hacen las multiplicaciones al estilo maya.
bruh literally what the fuck this mean
this is an actual way to do multiplication and its cool as hell.
what i want to know is what to do you do if any section adds up to an integer greater than ten? does that not happen or do you end up with like, oh, or do you just end up writing it all out normally?
I’ve never seen this before and i wish i knew it when i was going through the school system. i hated math growing up but now studying cool math things is a hobby of mine because it’s fascinating stuff that’s fun to play around with
this is basically a sneaky way to visualize the normal pen-and-paper way of doing multiplication (and also skip the memorized times-table part by manually counting out the individual multiplication results) and so you do basically the same thing as you would when multiplying normally. and i could try to explain this out a bunch in words but i felt like it would be easier just to throw together some shitty graphics to demonstrate, using the most egregious case of the situation you’re asking about that is possible with 2-digit numbers:
basically, whatever “extra” digits you have in one section spill over into the previous section, if that makes sense? or think of it as each time you move one section to the left, you also move exactly one digit to the left, regardless of how many digits are in the section or. yknow what just look at the picture hopefully it does a good enough job explaining
and if we look at the same picture again but with all the Hidden Math exposed…
it really is just the exact same thing as regular multiplication! the leftmost set of lines for each number represents the tens place and the rightmost set of lines represents the ones place, and by counting the intersections you literally are multiplying the numbers, sans the extra zeroes which you essentially add on when you position the numbers in the correct order
so like, the way and reason this method works actually makes complete sense once you work it out! and maybe for some people that like, ruins the “magic” of it or something but for me figuring out how tricks and things like this actually work just makes them all the cooler, not to mention making me feel like i can “trust” the method better if i decide to use it, since understanding how it works makes it feel less likely i’m going to mess something up, and less worried about the possibility of a case where the method breaks down and doesn’t work
also as a side note, obviously once you get to this point it does become impractical and tedious to actually count every single intersection, or even count the number in a row then add up by the number of rows, which is why multiplication was invented in the first place - as a shortcut for addition! math is cool when you actually get a grasp and understanding on how and why things work, it’s just a shame that 99% of math classes don’t focus on giving you a genuine understanding of underlying concepts and instead just teach you memorization or bark rules at you without stopping to ensure you know what you’re doing and why
