Add declaration for functions, depending on what it will return
The add method in the (Bc.php) file use (bcadd) function and it returns a string so I add a
String declaration.
The divide method in the (Bc.php) file use (bcdiv) function and it returns a string or null so I
add a String declaration with the possibility it can be nullable (?string).

I used the same concepts for other functions.
