How MMXXIX is built

Roman numerals are written one place value at a time, largest first. 2029 splits into 2000 (thousands) + 20 (tens) + 9 (ones), and each piece becomes its own group of symbols:

Read left to right, the symbols add up: 1000 + 1000 + 10 + 10 + 9 = 2029. MMXXIX uses one subtractive pair (IX) -- a smaller symbol placed before a larger one is subtracted, which is how Roman numerals avoid writing four of the same symbol in a row.

The symbol M (1000) is the largest one used to build MMXXIX, and 1 through 100 has no other number that uses it.
