Welcome to the forum! 
First of all; we have a dedicated sub-forum if you wish to ask any specific questions. This topic will likely be moved there soon.
I'm not very good at Maths, but believe it or not; I just did this question right through.
I have some incredibly messy working here. It gets to the right answer in the end, but again; I'm not exactly the most mathetically minded person in the world. I'm of a more linguistic nature.

Can't see why you shouldn't upload something like that.
Mabye another mod could clarify that.If you are helping with maths, sometimes it's easier to use the equation editer that comes with MS word to show your working and then upload an image.

If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you
But make allowance for their doubting too,
If you can wait and not be tired by waiting,
Or being lied about, don't deal in lies,
Or being hated, don't give way to hating,
And yet don't look too good, nor talk too wise:
Yours is the Earth and everything that's in it,
And--which is more--you'll be a Man, my son!
