The equation generator provides equations with seven versions of Roman numerals (including standard roman numerals, which are always the result on the right), indicated by different decorations on the text. The decorations and what they do, as well as the numeric values involved in the bottom equation, are as follows. For reference, the standard Roman numerals sequence is I=1, V=5, X=10, L=50, C=100, D=500, and M=1000.
DecorationInterpretationFinal Roman NumeralFinal Value
ItalicsI=1, and the letters are powers of 10, so V=10, X=100 MDCCCLXXI 1131201
Curly bracketsReverse the values of MDCLXVI; for example, D and V swap values. MMMCCCL 83
Small capsRoman numerals without subtraction. All letter values are added regardless of location. MMCMLXXXVIII 3188
Dotted underlineRoman numerals in base 6, so I=1,V=3,X=6,L=18, etc. MDXLI 337
LowercaseInterpret locations as decimal place values DLXII 5051011
BoxConcatenate each letter value as a string.
Computing the result of the equation gives that the answer is the Roman numeral that, when boxed, is equal to 100015050. Boxing a numeral concatenates the values of its letters, so the answer is MILL.
