TITLE: Is there a "greater than about" symbol?
QUESTION [53 upvotes]: To indicate approximate equality, one can use ≃, ≅, ~, ♎, or ≒.
I need to indicate an approximate inequality. Specifically, I know A is greater than a quantity of approximately B.
Is there a way to succinctly express this mathematically?

REPLY [65 votes]: LaTeX has the symbols \lessapprox ($\lessapprox$) and \gtrapprox ($\gtrapprox$).
Incidentally, a long time ago I came across this awesome Short Math Guide for $\LaTeX$, a free pdf by the American Mathematical Society. Well-worth keeping it close by.
