## On the Subject of Grimm

Let us just hope that life is not as grim as it is.

- Take the three digits to the left, right, and above the grimm symbol, and add, subtract, multiply, and divide the digit inside it to obtain 12 separate values. These values can be negative.
- After arranging these values from greatest to least, take the highest and subtract the second highest from it. Keep subtracting the next highest until you have subtracted it by the lowest of the set.
- If when subtracting, the result is in the negatives from the current value, add that value instead and make this your new result.
- Take the ones digit of this result and call this the grimm.
- If the digit underneath the grimm symbol matches this grimm, press the yes button. If it is not, press the no button.

Do not round at any time. Incorrect presses will result in a new combination being generated.
