Math symbols in LaTeX

Updated:

Relation and operation symbols have short commands. Learn a dozen of them and you can write most physics and calculus formulas. Number set symbols need the amssymb package.

Relations

Open in editor 
a \le b, \quad a \ge b, \quad a \neq b, \quad a \approx b, \quad a \propto b
a≤b,a≥b,a≠b,a≈b,a∝ba \le b, \quad a \ge b, \quad a \neq b, \quad a \approx b, \quad a \propto b
