I feel bad for not remembering this. But it was a LONG time ago that i was tought what it ment.

Here it is:

What does > mean??

OR < ???

If i remember correctly. If someone says the like apples more than oranges. Then it can be written like this:

Apples > Oranges
OR
Oranges < Apples

Or something like that.

You know i kind of blame my teacher for me not remebering it, because the way they tought me was that the > or < was a mouth (Or to give you a better idea, a "Pac-Man" like object). Which if i pointed it to the left, ment i would rather eat from the left than the right, and vis versa.
