Using Reserved Operators
In general, you can use any reserved operator inside a string except the single quote operator
Examples
Using quotes inside a string:
'my "string"'
'my"-"string'
Using arithmetic operator inside a string:
'my + string'
'my * string'
Use a backslash to enter an escape sequence, as an example to embed single quotes in a string:
'my \'string'
The resulting string will be my 'string.
