#3 - I don't see how this will help people with asthma, unless they have some multiplication problems to solve?
Cool concept, i wish i knew about this back in school.

Mkey, but is hard work for 123 x 321 to count the dots, it can be easier :
123+

First time i found this method was a couple years back on metacafe..oh here i found the link for ya http://www.metacafe.com/watch/296904/easy_graphical_multiplication_trick/

No big deal:
(a + b) x (c + d) = ac + bc + ad + bd
So counting the dots are the ac, bc + ad and bd.
Simple expansions.
Louise Pascale had a Triangle named after him.
For the clueless see:
(20 + 1) x (10 + 3) = 200 + (60 + 10) + 3

I thought everyone had a calculator on their phone now. this is useless. And don't say but what if your battery dies. If your battery dies life isn't worth living anyway so who cares about the sum.

It only works good with small numbers. for example: 98 x 79 will be hard to do using this method.

This is a waste of time.
Try doing something like...
97 x 89 =
Take you forever counting the crosses.

you don't even need a paper to do those operations... besides you can do it faster with the old school method.

it does work but it becomes a long thing when doing long multiplication...maybe a abacus would solve it quicker? who knows..
