Following your logic, why excel anything at all?

Or it just makes their brain 50 times more powerful than yours...

This is awesome! As someone at university, its like why weren't we taught this!... for starters its actually faster than a calculator... takes as long to learn... and in the end you can just throw it out and "imagine" the abacus as we see it here. Far superior to calculators... imagine all those square roots and multi variable algerbra for calculus would be almost entirely mental!

@ZombieJesusBrainz Because it's useless. It doesn't matter how fast you can do mental calculations. In the real world people use computers for these types of mundane calculations, and they are always going to be faster.

Sounds like someone's been watching too many zeitgeist-type movies.

Fractional reserve banking industry in America dosnt want you to know math or you might get wise to the fraud of fiat specie. "Keep em dumb and in debt for paper" is the industry motto. Americas bankers monetary monopoly will never allow a well educated public without life crippling debt.

Maybe some schools are actually unaware of the abacus perhaps some teachers no of it and our teachers should at things like meetings should talk about it as an idea.

[snylekkie]

Well no. Abacus can't find 6-th grade roots or crazy tangents and integrations.

It's just multiplying at blinding speed.

kids do deserve all, society fucks them up.... without exception.

why tape this..i don't see the point of taking this video..i think abacus just makes things easier.Like for pre-schoolers, with abacus, they can count faster and improve their memory. what's so bad about that? it's just efficient.

Sounds like you're trying to discourage learning and wish everybody to remain ignorant.
