 However, there is no zero value available, so Roman numerals represent powers of 10 with different letters (I, X, C, and M), not by position (1, 10, 100, 1000, etc).
 
 The approaches to this exercise break down into two groups, with many variants in each:
+
 1. Split the input number into digits, and translate each separately.
 2. Iterate through the Roman numbers, from large to small, and convert the largest valid number at each step.

 ## Loop over Romans approaches
 
 In this class of approaches we:
+
 1. Create a mapping from Roman to Arabic numbers, in some suitable format. (_`dicts` or `tuples` work well._)
 2. Iterate nested loops, a `for` and a `while`, in either order.
 3. At each step, append the largest possible Roman number to a list and subtract the corresponding value from the number being converted.

 These five solutions all share some common features:
+
 - Some sort of translation lookup.
 - Nested loops, a `while` and a `for`, in either order (except the last one).
 - At each step, find the largest number that can be subtracted from the decimal input and appended to the Roman representation.
