What is CXXIII?

CXXIII is just a special way to write the number 123 using letters instead of numbers.

Imagine you're playing with blocks in your toy box. You have one big red block, two medium blue blocks, and three small green blocks. If you line them up together, that’s 123, like counting how many blocks you have in total!

Now think of each letter as a kind of block:

• C stands for 100 (like the big red block),
• XX is two 10s (like two medium blue blocks),
• III are three 1s (like three small green blocks).

So putting them all together, C + XX + III, gives you 123, just like your toy blocks.

Roman numerals use special letters to stand for numbers:

CXXIII uses C (100), X (10) twice, and I (1) three times, like having different types of blocks to make a bigger number.
