I started going to the gym. I try to go a lift some heavy things and than swim for a while. I have to trick myself to keep swimming cause I start thinking of all the things that I'm going to have to do during the day and then I stop swimming sooner than I should.
So I started calculating squares while I was swimming.
78^2, 99^2, 56^2, etc...
Then checking them on my phone later.

So I did a couple of squares that were close together.
25^2 and 26^2.
Being a software dude, I decided there had to be a better algorithm... then I realized that 26^2 was just 25^2+25+26 = 676

I was sort of stunned.. and then figured it out for a bunch of other squares. Then realized that
(x+1)^2 = x^2 + 2x + 1

Which looks very familiar.. but I'm way too many years out of math class.
I just surprised myself while swimming back and forth in a pool.
