The neck maths is strangling me.

ETA: Disregard - I can't read. (Multiple times. I'll just go back to primary school now...)

I feel incredibly silly, because I hit this problem last time, made a post about it, and got help from a friend. But I can't find the post (I think it was a year ago) and the friend's just gone on holiday, so I'm throwing myself on your mercy. I seem to remember it was something blindingly obvious, and yet...

So I'm trying to make a jumper using this page. Done my swatch, comes out 4.4 stitches to the inch, all good. So I fill in my maths for the neck like so:
Back-stitches: 22 = total-neck-stitches: 64 × 0.33

Sleeve-stitches: 16 = back-stitches: 64 × 0.25

Increase-stitches: 8 (this is a fixed number)

The front then gets the remainder of the stitches, which is calculated as the total stitches minus the sum of the back, two sleeves, and the 8 increase stitches:

Front-stitches:_______ = total-neck-stitches: 64 - (back-stitches: 22 + sleeve-stitches: 16 + sleeve-stitches: 16 + 8)

*screeches to a halt* Back + Sleeve + Sleeve + 8 = 62. Which gives me 2 stitches left over. Which is wrong, it's where I went wrong last time, and I can't remember why.

Help?
