DXCVII

DXCVII is a Roman numeral. It uses the standard set of symbols where D represents 500, X represents 10, C represents 100, V represents 5, and I represents 1. In this sequence, the X precedes C, forming the subtractive pair XC, which equals 90. The D contributes 500, and the remaining VII contributes 7 (5 + 2). Taken together, the value of DXCVII is 500 + 90 + 7 = 597.

The notation DXCVII demonstrates how subtractive notation can appear within a larger numeral. The XC pair indicates 90, and the trailing VII adds 7 to the total. While this form is valid under traditional Roman numeral rules, it is less common than some other representations of nearby values, and it may look unusual to readers expecting more regular groupings such as DCXCVII for other numbers.

In general, Roman numerals are used in clocks, monuments, book chapter headings, and other contexts requiring a classical numbering system. The specific sequence DXCVII is primarily of interest as a compact way to encode 597 using a subtractive pair (XC) within a larger numeral.
