The mnemonic I made up for that sign when I was little is that it's Pac-Man, and he eats the big numbers. I was a bit of a video game nerd.
I was taught at school (30-mumble) years ago, to imagine a Very Hungry Crocodile. He *always* wants to eat the bigger number. I *still* have to use that imagery.
But then again, I still need to use my fingers to do the nine times table.
Hey, I got the crocodile story too, and yes, still use it
But I get really confused if there's only one number, like ">50% of students filled the application", I never know if it's supposed to mean fewer or more than 50%...
