While an equality A=B states that two mathematical expressions are equal, an inequation A!=B states that two expressions are not equal.

A strong inequality in which a is not only less than b, but much less (by some convention) is denoted a<<b.

A quantity that is nonzero everywhere is said to be nonvanishing. For instance, the values of x^2+1 are nonvanishing for real x, while those of x^2 are not (since x^2 ...

The term "over" is commonly used in mathematical exposition as a synonym for "in the domain of." So, for example, "Let f be a function over the reals" means "Let f be a ...
