Basic Math

This is a variant sudoku puzzle.

Rules:

1. Normal sudoku rules apply.

2. Digits on a thermometer must increase from the bulb end.

3. Cells separated by a knight’s move in chess must not contain the same digits.

4. Digits cannot appear in the same relative position within different box regions (e.g. r1c1 and r4c4 cannot be the same digits).

5. Cages with the same letter must contain the same digits. Cages with a formula must equal the referenced cage plus or minus the given amount. Cages with the same formula must contain the same digits to equal the sum. Cages with different formulas do not necessarily have to contain different digits.
