New Math, Tom Lehrer

[@heyy13]

I love that you used pictures of rubbers (erasers) instead of pictures of blackboard erasers which is what he was refering too. xD Also great expression of the second half of the song.

[@JobzSuckz]

My math teacher played this for us in the class today.. And he wanted us to memorise all of it. D:

[@johnchessant3012]

For 342 - 173, why not do 342 - 200 and then add back 27? (since 200 - 173 = 27) Then in base 8, you can use the same method: 200 - 173 = 5, so do 342 - 200 and then add back 5.

I hope my video "Calculus for 6th Graders" is much easier to follow. Calculus is much more directly connected to basic arithmetic than you might think.

i showed this to my mother, who grew up learning the old math, and is now an elementary school math teacher teaching the "New Math", She basically peed her pants because she can relate to ALL of this XD. She even teaches different base systems like base 8 XD

[@JohnDoesSports]

This video, and my math teachers of course, have helped me understand how to do math with different bases. It's really simple when you begin to touch upon the concept.

[@ByrdieW]

Wow. You actually animated the entire song. Thank you! :)

[@gnyhwy]

It's crazy to me how this is considered new. I was taught this way in the mid 70s, 3 1/2 decades ago, which is before a lot of teachers working now were even born.

[@Muttyfut]

@DDDGamer Whoops, I was trying to memorise the song (I'm a massive nerd) and I just needed to skip to the actual song. Thanks for putting the first bit there though, it's rather amusing.

[@Brainiac12000]

I've memorised this!

[@DenisZholob]

@982alexander yep, you can do arithmetic in any base, the most common however are base 10 (our decimal system) and base 2 (binary, used by computers to represent the "on" and "off" states)

[@DenisZholob]

@JobzSuckz Awesome, but memorizing this would be useless, but fun i guess. Another version of this was played during my programming class (forget why) and that inspired me to create a better one. And this is the result.

[@JoyGrenade]

This broke my brain.

[@starponys0740]

If students should be taught any other bases than 10, it should be training in case they want to be programmers. In other words, don't teach base 8 - teach bases 2 and 16 (binary and hexadecimal).

[@starponys0740]

The way I remember subtraction is this: For the problem 342 - 173, slash the 3 and write 2. Carry the 10 to the 4 to make 14. Then slash 14 and write 13 - and carry the 10 to the 2, writing 12. The confusion of the "New Math" approach (and even one of the traditional approaches) is to start the subtraction with the last digit rather than the first. The most intuitive, straightforward method is the way I learned. And, in the end, it teaches the greatest appreciation for place values.

[@DenisZholob]

@Muttyfut Yep that's where the vid picks up.

[@TeeGeeFan]

This was written in the 60s.

[@PSlappy02]

at 2:38 the picture of the hands is not missing thumbs

[@manfredatee]

I'm pretty sure that the erasers he means are blackboard erasers, not pencil erasers.

[@Bibledigger322]

Why did anyone even attempt New Math?

[@982alexander]

i dint know there was a ''base 8''...

[@clivegoodman16]

You can have a base of any integer greater than 1. Computers generally work in base 2 (known as binary) but it is common for computer scientists to use base 8 (octal) or base 16 (hexadecimal). The ancient Babylonians used base 60.

[@AbsoluteQualityAQ]

Sorry for my english)) It always was* like this))) (or smth like that)

[@AbsoluteQualityAQ]

It always be like this -_-

[@yourfellowscratchjrenthusiast]

[@TheFireMiner]

would be harder in base 16...

[@AsheandCinders]

2 people didn't get 1
