## On the Subject of Cistercian Numbers

Are you smarter than a medieval monk?

The module has a math problem written in the Cistercian numeral system, as well as a numpad to submit your answer. Each Cistercian numeral represents a number from 1 to 9999. Submitting the correct answer will solve the module. Submitting an incorrect answer will strike. Leading zeroes and decimals are ignored. The display caps out at 4 digits; only enter the four rightmost digits.

The numerals are each built out of one or more pieces, each representing a digit. The absence of a piece represents the digit 0. The pieces are flipped about one or both axes to indicate place value; the precise appearances of the pieces, the way different places are formed, and a few examples, can be found in the chart below.
