+Next, the [`str.startswith()`][startswith] and [`isdigit`][isdigit] methods are used to see if the remaining characters in the input are either negative or positive digits.
+Because "-" is used to denote negative numbers, `str.startswith("-")` is used in the first condition and `question[1:].isdigit()` is then used for the remaining string.
+If the `str.isdigit()` checks pass, the [`int()`][int-constructor] constructor is used to return the string as an integer with the proper sign.
 
 Next, the elements in the `OPS` dictionary are iterated over.
 If the key name is in the input, then the [`str.replace`][replace] method is used to replace the name in the input with the `dunder-method` value.
