I Think I Need To Take Remedial Math

I started working, this weekend, on a small video game shelf, basically a DVD rack, for our living room, and everything was going pretty much the way I intended. Cut up the pieces, sanded ’em.

I went to put it together and realized that I can’t count. If you want 4 shelves, and you want the thing to have a top, you need to count to 5! Uggh. If I’d counted to 5, I wouldn’t have to go back to the store to get another piece of lumber, as I would have made each of the shelves half an inch shorter, thus making the last cutoff long enough for the fifth piece. Instead, I have to wait until I can get back to the store, which, hopefully, will be in the next half hour.
