Photoshop’s blend modes explained

I’ve used Photoshop for so long, I used to keep a backup copy of it on a floppy disk. Nonetheless, I’ve never really known how the blend modes worked. I simply experimented until wither my file looked the way I wanted it or I abandoned the exploration altogether (which was usually the case). Decades later, I come across this explanation. Too bad I don’t design much anymore.
