#3 - I don't see how this will help people with asthma, unless they have some multiplication problems to solve?

@14 leave a "space".. no lines maybe?

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.
