    How MMXXI is built

    Roman numerals are written one decimal place at a time, largest first.

    1. MMthousands · 2MM is 2 × M (1,000), written out 2 times.
    2. XXtens · 2X written 2 times: 2 × 10 = 20.
    3. Iones · 1I is 1.

    2,000 + 20 + 1 = 2,021

    No subtraction is needed here: every letter is the same size or smaller than the one before it, so you simply add them up.
