This one was tricky!

Spoiler

The non linear flow of numbers caught me up and my first solve was the wrong result! Thankful for the multi-row tool!

This one was super fun!  I was feeling pretty clever about my method for calculating the numeral values, but got hung up on evaluating the formula.

I hadn't used the Dynamic Replace tool before.  It seems really useful, but I have no idea how or why it works.

Here's my solution. I came up with the correct answer, but I feel I've missed something. I'll check the solution now...

Started out pretty easy, but have to admit, learned a little something with the dynamic replace. That's a slick  trick.

Tried with regex to deal with IX, which is no very dynamic, then noticed Martin's multi-row formula which is so much easier.

And that solution with dynamic replace is amazing.
