I love math...but I didn’t know this. Much nerd fun.
Years ago I tried to learn the Trachtenberg system of system of speed math. I still couldn’t get it!
I thought heaven had come down to earth when the first hand held calculator went on the market.
When I was young I liked math and scored 99th percentile on the Florida Senior Placement Test. That was as high as one could score.
I recently bought a nice TI calculator and could not even figure out how to work it.
On the other hand my verbal skills do not seem to have gone down.
Nice! Thanks for posting.
Way cool, thanks !
loved it. thanks.
I would like a “deep” math lesson that demonstrated to me WHY this little “trick” works. That - even more “nerdy”, yes, would be very interesting as well.
I’ve seen similar videos which I found interesting, but the traditional methods are actually shortcuts compared to these esoteric methods.
What is truly a waste of time are the “NEW” “ENLIGHTENED” methods such as the old NEW MATH and the crap Common Core shoves down teachers’ throats. The time spent screwing around with this nonsense would be better spent in practice, which builds automaticity. Once you just KNOW the results of fundamental computations, you can discard all the methods. Then higher math is a breeze.

Sounds fun!!
That’s crazy! Very interesting.
That IS fun! He keeps talking about “your workbooks”. Have any idea where to get those? I binged and checked Amazon - no joy. Would love to teach this to my GDaughter who has been FREAKING traumatized by Common Core math.
For fun, Anyone who has never heard Tom Lehrer: New Math (concert live) (1965) https://www.youtube.com/watch?v=W6OaYPVueW4

Just great! I missed the other 4 parts and now will be ignorant in math.... too.
Math is no longer needed.
Cal State will no longer require placement exams and remedial classes for freshmen

They need to teach compound interest in high school.
