What is 300 in Roman numerals?
How CCC is formed
Reading left to right, 300 breaks into these additive parts. Each Roman symbol is added in turn to reach the total.
C + C + C = 100 + 100 + 100 = 300.
The shape of CCC
- Written out, CCC runs 3 characters, against 6 for 299 (CCXCIX) and 4 for 301 (CCCI).
- No part of CCC is subtractive: each glyph adds to the running total, so the numeral reads straight through from left to right.
- CCC anchors its whole hundred: every numeral from 300 to 399 opens with CCC, and the letters after that opening carry the rest.
- CCC draws on 1 of the seven symbols, with C doing the most work at 3 appearances.
- Among 300 to 309, 300 is the most compact: no other numeral in its ten gets down to 3 characters.
