For those who chose not use a macro or dynamic replace, I recommend that you check that you pass this one:
MDCCXXXII * LXXIX / IX + I * VII = 15210.111
Order of operands matter. @patrick_digan fancy the challenge?
@Niklas I built a simple solution which just does 2 passes with the multi-row formula, one for multiplication and division with a second pass for addition and subtraction. It's not very pretty at this point...
This was a fun one! I didn't match the provided solution due to evaluating in PEMDAS order as others have already mentioned.
Once I figured out that I needed to incorporate a solve for the numerals equaling 4 and 9 I was able to get the right answer. Fun challenge!
