I was wondering about this, just now, because I was trying to write something like:
$880$ is not greater than $950$.
I am wondering this because there is a 'not equal to': $\not=$
Not equal to is an accepted mathematical symbol - so would this be acceptable: $\not>$?
I was searching around but I couldn't find any qualified sites that would point me in that direction.
So, I would like to know if there are symbols for, not greater, less than, less than or equal to, greater than or equal to x.
Thanks for your help and time!
