Vedic maths

starn

Is anyone familiar with Vedic Maths. I understand it is great for speading up mental aritmatic. In school I had been able to do third and forth level differential equation in my noggin. I have since fallen out of practice of doing this. At the moment I'am trying to get myself back up to speed on a few things, were this leve of mental artitmatic would clearly be of advantage can anyone suggest some books or web sites to use as a springboard into world of Vedic Maths

Here's a link to some of the basics:

It's a nice system, but it all depends on how your mind works.

Heh. I thought this was the geekiest troll... perhaps not.

Vertically and Crosswise (As you were accustomed to the system previously)

It looks like it could speed things up consierably.

There is a six week Vedic maths course that runs for six weeks, and the first week is free. the first week teaches you multiplication.

It's free whether you sign up to the course or not!:D

That's usually a good length for a 6 week course!

My thoughts exactly.

Vedic mathematics is an ancient Indian science. Its amazingly simplifies the the tough calculations by using some simple tricks.

For those who are interested, there are lots of interesting Vedic Mathematic discussions over here -

Hey all,

For those of you interested in some neat maths shortcuts, there is a pdf here http://vedic-maths-ebook.com/Memorymentor_Maths_tips.pdf for free.

I never seen that before,
vertical and crossways is intersting
When in school our teacher like up to do powers in our head, i was pretty good and cam up with a similar system, round up and count back.

Take 19^2, round up to 20 and square
=400, count back by subtracting 20 and 19
=361
You jsut use a power you know and count back, if you need to go more than one number, ie the nearest you know is 3 away, then you just subtract more.
17 from 20 would be 400-20-19-19-18-18-17

it works with adding too obviously
It works where you know a nearby power, but the one you need.
Say you need 31^2
30^2 =900
900 + 30 + 31 = 961 = 31^2

multiples of 10 are simply, square the number add two 0s,
And numbers ending in 5 folow a pattern too
(N5)^2 =N x N+1, and stick 25 on the end
so
65=6x7=42, then stick on 25=4225


so you should never have to count more than 2 places up or down

....this may be not be new to everyone, but I was 16 or 17 when I came up with it myself.
