I saw someone was having problems with their site before so I'm now adding the problem content to my git.

From the looks of it the difficulty is going up a little.

Learned: Regex (short for regular expressions) is a powerful tool for searching, matching, and manipulating strings. It is often used for tasks like pattern matching, text validation, and extracting specific parts of strings.

mul: Matches the literal word "mul".
( and ): Matches the opening and closing parentheses ( and ).
\s*: Matches any amount of whitespace (spaces, tabs, etc.), including none.
(\d+): Captures one or more digits (numbers) in a group. The parentheses () create a capture group, so the digits can be accessed separately.
,: Matches the comma between the two numbers.
\s* (again): Matches optional whitespace around the comma.

I tested it with the \d+ and it did return the same result but they could have thrown a curve ball with a long number. So I did \d{1,3}.

Good catch on the optional whitespace. I didn't do that but they were forgiving.

Any luck on the part 2?

oh, lol, there is a part 2? maybe not now, but i'll read the question better tomorrow! :-)
