(*) Starred explanations indicate that the operator requires integer arguments.

## Unary

```The following is a list of all the unary operators and their usages:

Symbol      Example    Explanation
-           -a          unary minus
+           +a          unary plus (no-operation)
~           ~a        * one's complement
!           !a        * logical negation
!           a!        * factorial
\$           \$3        * call arg/column during using manipulation
```

## Binary

```The following is a list of all the binary operators and their usages:

Symbol       Example      Explanation
**          a**b          exponentiation
*           a*b           multiplication
/           a/b           division
%           a%b         * modulo
+           a+b           addition
-           a-b           subtraction
==          a==b          equality
!=          a!=b          inequality
<           a<b           less than
<=          a<=b          less than or equal to
>           a>b           greater than
>=          a>=b          greater than or equal to
&           a&b         * bitwise AND
^           a^b         * bitwise exclusive OR
|           a|b         * bitwise inclusive OR
&&          a&&b        * logical AND
||          a||b        * logical OR
```

## Ternary
