Hypertext Help with LaTeX

Binary and relational operators

Some "math" symbols are obtained by typing the corresponding keyboard character. Examples include

    + - = < >

Note: plus, minus, and equal sign may be used in either text or math mode, but < and > are math mode only (they produce inverted exclamation and question marks, respectively, in text mode).

The following commands may be used only in math mode.

Note that "greater than" and "less than" are obtained simply by entering > and <.

A slash, indicating "not" can be placed through a symbol (or a letter) with the \not command. For example, not less than is


and not less than or equal to is


If the slash isn't properly positioned it can be moved by putting a math mode spacing command between the \not and the symbol.
