MCD
1,400 is written MCD in Roman numerals. That is 2 symbol groups added together, reading left to right from the largest value down.

| M | 1,000 | — | 1,000 |
| CD | 400 | D − C | 1,400 |
Why the smaller symbol comes first
MCD uses subtractive notation in one place: CD means D minus C, or 400. A smaller symbol placed before a larger one is subtracted from it rather than added, which is why IX is nine and not eleven.
Only six such pairs are valid — IV, IX, XL, XC, CD and CM. That restriction is what makes the notation unambiguous: IIII and IC both look like they should work, but neither is standard, and only one spelling of any number is correct.
