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.

Decoration	Interpretation	Final Roman Numeral	Final Value
Italics	I=1, and the letters are powers of 10, so V=10, X=100	MDCCCLXXI	1131201
Curly brackets	Reverse the values of MDCLXVI; for example, D and V swap values.	MMMCCCL	83
Small caps	Roman numerals without subtraction. All letter values are added regardless of location.	MMCMLXXXVIII	3188
Dotted underline	Roman numerals in base 6, so I=1,V=3,X=6,L=18, etc.	MDXLI	337
Lowercase	Interpret locations as decimal place values	DLXII	5051011
Box	Concatenate 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.
