This is probably just me, but I always tend to write a bigger number in the right, so that I can picture a number line in my head.

(Which means I rarely use > and >= operators. It's always < or <=.)

Now, come to think about it, this might have something to do with my native language (Japanese). In Japanese, where the verb always comes at the end of a sentence, you can say "a < b" and "b > a" using the same order and same adjective.

   a < b ... a -than b -toward bigger (a よりも b のほうが 大きい)
   b > a ... b -toward a -than bigger (b のほうが a よりも 大きい)
