number	concatenation	addition	addition to each of the array's elements

number	remove first characters from stack	subtraction	subtraction to each of the array's elements
* the times operator
string

space			sums up all the elements of the array (stackMode becomes float)
/ the slash operator
string

regex	return matches of regex and convert to array mode
S convert to string (only a monad when stringMode is array)
