CCCXCVI is a Roman numeral that represents the number 3961.

To convert CCCXCVI to numbers, we can use the following rules:

The value of a Roman numeral is the sum of the values of its symbols, except when a smaller symbol precedes a larger one, in which case we subtract the smaller value from the larger one.

The symbols I, X, C, and M can be repeated up to three times in a row, but not more. The symbols V, L, and D cannot be repeated.

The symbols I, X, and C can be placed before the next higher value symbol to subtract their value. For example, IV = 4, IX = 9, XL = 40, XC = 90, CD = 400, CM = 900.

Using these rules, we can write CCCXCVI as:

CCCXCVI = (C + C + C) + (X + C) + (V + I) = (100 + 100 + 100) + (10 + 100) + (5 + 1) = 300 + 110 + 6 = 416

Therefore, CCCXCVI in numbers is 416.
