what's is the difference between '<' and '>' and how do you easily remember it?
The larger side is on the side of the larger number, i.e.
10>5
-2<2
100>10
To remember, simply imagine " < " as a Pacman who wants to eat the most food. Since 5 food is more than 3 food, 5 > 3.
The shape is like a funnel. The bigger number sits at the bigger side of the funnel.
