Where can I learn "Quick" math - Help

Hi,

I don't mave MUCH of a Math back ground, mainly math used for the line of work I am in (Currency Analyst) and programming.

However, i was just inspired by a film I watched about a math expert, who can do calculations in his head like 89 x 437, in like 5 seconds.

Is there a site, or anything learning material that teaches you "Qucik" math that you can do in your head? I am not sure If I am explaining my self correct here, so just let me know. If not, ill try to be more specific.

Any help would be great, thanks!

Hummm, you might be out of luck, unless you're a savant genius. If your looking to impress the ladies, I don't think that's the best way :rofl:

Hey

Yea thought so :)

I don't mean I want to do the calculation in my head in 5 seconds, just being able to do large multiplication calculations in my head you know.

I thought I seen once a website that had a program that can teach you to do large multiplication calculations...hmmm, could be wrong.

Thanks anyways, appreciate it!

I know there are a few tricks to doing things like that in your head but I have forgotten them. The best way though would just be to practice. Start small and just slowly build up to larger numbers.

I read once, years ago, of a guy who, while being in a Nazi concentration camp, perfected a mental math system, and wrote a book on it. (Also I read of some guy who used to do a lot of mental math to stay mentally active, while in a Japanese concentation camp.) But at this point I can not remember more.

PS: I see tronter is correct: "Mental math system was developed during the Second World War in the Nazi Concentration Camp by a Ukrainian Mathematician Jakow Trachtenberg"

Hey

Have you read Trachtenberg's book? Can you tell me a little about it, before I drop \$90 on it :) ?

Thanks!

what kind of "quick math" are you talking about? just number crunching?

Mainly large multiplication - 3943 x 94 , 12 x 385, and so on for a start.

Look into Vedic Mathematics. Its pretty simple once you learn the rules and do a lot of practice (with emphasis on practice).

I've seen 6 year old kids that can do huge amounts of number crunching in a few seconds. Its amazing! My mom is an instructor for such programs. (http://www.ucmas.com/). But you have to start from a very young age.

Hi the_force,
I figured it out that you are in need of basic mathematics.

Well Mental Math at https://www.esumz.com adds to online Mathematics.

Cheers!!
