37 in Roman numerals

37 is written XXXVII. In chunks: X (10) + X (10) + X (10) + V (5) + I (1) + I (1) = 37.

The answer

XXXVII

37 in Roman numerals is XXXVII.

How XXXVII is built

To write it, split 37 into 30 + 7. 30 is XXX, 7 is VII, so 37 is XXX then VII: XXXVII.

To read it, XXXVII has 6 chunks, and none of them is a take-away pair, so every chunk is added.

The mistake to watch for

Writing 37 as XXXIIIIIII

Wrong: XXXIIIIIII

XXXIIIIIII counts in ones, like a tally, and writes I more than three times in a row. Use V for five: 7 is VII, which makes 37 XXXVII.
