I honestly don't understand how people struggle with this, but maybe it's some kind of light dyslexia. I don't judge people with dyslexia, obviously. It's easy for me, as someone who doesn't have dyslexia, to claim it is easy to see.
I don't know about everyone else but before I figured out the visual clues of the symbols on my own, the only explanation I ever got was "> is greater than, < is less than" but I was a kid and there was nothing stopping me from interpreting "10 < 100" as "100 is less than 10" which confused the hell out of me.
