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.
- \pm plus or minus sign
- \mp minus or plus sign
- \times times (an "x")
- \div divided by sign
- \ast an asterisk (centered)
- \star a five-point star (centered)
- \bullet a bullet
- \circ an open bullet
- \cdot a centered dot (see also,
- \leq less than or equal to
- \ll much less than
- \subset is a subset of
- \geq greater than or equal to
- \gg much greater than
- \equiv equivalence symbol
- \sim similar to
- \simeq similar or equal to
- \approx approximately equal to
- \neq not equal to
- \per "perpendicular to" symbols
- \propto proportional to
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.
