I came across this on youtube (of course).
I’m always looking for neat math tricks and shortcuts.
This is actually a not-so-new solution to multiplying big numbers by hand.
It’s really impressive. Be patient. The setup takes a bit but you’ll see once everything is gridded, it makes multiplication sooooo much easier.
ha ha ha ha!
Ah HAH! I knew it! DSO’s gonna love this; what with his math phobia 😉
Do you know the grid-based multiplication technique that this is a backhanded reference to?
well of course
Why, of course. That makes problems such as these so much easier. A pity he neglected to draw in the graphing function.
