comment How hard should a mathematician work?
On the other hand this is a new user who has 7 reputation (you start with 10) and you people have down voted him twice... The comment is beneficial for learning, the down-votes at this stage in his/her account is just discouraging. +1

comment Two children paradox : where is my reasoning wrong?
Ahh well the main problem here is that it's not just GG, GB, BG, BB ... if order matter like the difference between GB & BG then you also have to have the difference between the girls... girl_1 then girl_2 or girl_2 then girl_1, so your real data set is: gg, gg, gb, bg, bb, bb — Which still equates to 50% chance it's a boy, not 66.666%

comment Two children paradox : where is my reasoning wrong?
I don't understand.. wasn't the whole point of the original 4 possibilities GG, GB, BG, BB already sorted by youngest and oldest? Otherwise what is the real difference between GB and BG?

comment what will be its value at the end of $10$ year?
I think the digression is the previous number minus 3 divided by the year. For example 15... year 2 = 15-(3/2) ... year 3 = 15-(3/2)-(3/3) ... year 4 = 15-(3/2)-(3/3)-(3/4) .. etc

Not enough information, there are a lot of different things that could fit your digression pattern of 15, 13.5, 12

comment Is computer science a branch of mathematics?
Just because something uses a bunch of math does not make it a branch of math... otherwise physics would be a branch of math.

comment How to solve a system of equations with only integers
@MatthewConroy Doesn't seem relevant, but okay... I'm programming a grid that displays images. Either 1 image with a widthxheight of axa and a cushioned region between the edges of the screen with width or length y. The 2x2 grid has images with widthxheight bxb and I want the cushioning constant. "y". The 3x3 grid has images with widthxheight cxc. Since I'm dealing with pixels on a screen it must be integers because I can't light up half of a pixel or a third of a pixel.

@MatthewConroy Nothing, I don't know how to approach the problem, that's why I asked.
