I never understood why so many people seemingly struggle with these signs to the point they need a mnemonic. The big side points to the big number and the small side to the small one. What even is there to remember?
Yeah, the symbol is the mnemonic. What does the crocodile even explain? Why doesn't the bigger number eat the smaller numbers?
Yeah. It would be like saying "Oh, when I see a stop sign, I think to myself they're the same colour a traffic light turns to when you're supposed to stop, so I remember to stop"
What you describe is a mnemonic.
Technically. That's not the point, though. The symbol itself has a built in mnemonic; it's designed so you can't forget what it means. If you wanna be pedantic, which, fair enough, we're talking about math notation after all, add "different" before "mnemonic" in the original comment and the point still stands.
