Naw, you just did less impossible stuff.

THEY!!111 OMG WTF LOL LET DA NOMADS AND TEH S3D3NTARY PEOPLA BOTH MAEK BITER AXP3REINCES
AND TEH GRAAT SINS OF THERE [DOCTRINAL] INOVATIONS BQU3ATH3D SMAL
AND!!1!11!!! LOL JUST IN CAES A DISPUTANT CALS U 2 DISPUT3 ABOUT THEYRE CLAMES
DO NOT THAN DISPUT3 ON THEM 3XCAPT BY WAY OF AN 3XTARNAL DISPUTA!!!!11!! WTF -
What's the point of this thread? The methods expalined in the video are alright, not all equally simple but still effective. You might argue the simplest method (the first one explained in the video) is best for a kid, but showing kids that maths work in different ways can only be good for their understanding of the matter.
Excessive calculator use is a general phenomenon in our societies, since it's easier than doing the math in your head. Congrats to aneeshm for the conscious decision to do without one, as would I, but I don't see the problem really.
Maybe I'm just missing the wood for the trees, but I find it more likely aneesh is just trying to put minor issues into big cultural pictures. Again. I'm afraid I need to know more about Hindu civilization etc pp...Comment

In High school I was allowed to use a slide rule in physics. Nothing in any mathmatics class. A slide rule would do more than a calculator back then anyway. hehe...yep, I'm old"I am sick and tired of people who say that if you debate and you disagree with this administration somehow you're not patriotic.

Are you studying at the IIT?Originally posted by aneeshm
Yes.
And damn proud of it!
Hah!
We learnt how to do all that impossible stuff in our heads, because we had to (the IIT-JEE and the AIEEE demand it - you aren't given enough space on the paper to even write out the logarithms).Comment

Knowing the algorithms is important, but if accuracy is king(such as at a job), just use a machine to do it.
and yea, those other methods are retarded, and won't scale to larger problems.Comment

I don't think that there are serious scalability problems about method, but the chance for errors are high - they aren't exactly KISS.

I got bored after not too long, so I won't comment on the entire video.
The usual algorithm that she first explained should be taught to everyone, period.
The "cluster" thing is something that's useful for calculations in your head, and I've been doing it for a long time, although I've never been taught it or heard it called the "cluster method" before today.
Obviously, with problems like 998*1350, there's a shortcut to use, and you should take it. But I don't believe that sort of shortcut is an efficient method for all multiplication problems, and it shouldn't be treated as such."You're the biggest user of hindsight that I've ever known.

Sinbad does a great bit where's he's buying lunch at McDonald's for $4.95 when the power goes out. Without the register, the cashier can't figure out change for a $5. He calls a manager over, who also can't figure it out. Finally, the cashier raises his hands in defeat, backs away from the register and say, "Just reach in and that what you think you have coming."

Be reasonable, how many 8 hour long math tests have you had to take where even one mistake failed you?Comment

When did aneeshm get any training in teaching kids math?I drank beer. I like beer. I still like beer. ... Do you like beer Senator?

That actually happened to me once, at a Burger King in Pittsburgh. They were using a computerized cash register -- one that didn't even have numbers, just pictures of the food -- and it crashed. Nobody but the manager seemed to have a clue as to how you would add the various prices together, add on an additional 7% sales tax, and then subtract the total from the 10 I was holding.
