* The result has a scale of `max($this->scale, $that->scale)`.
*
* @param \Arki\Math\Number|int|float|string $that The number to subtract. Must be convertible to a BigDecimal.
*
* @return BigDecimal The result.
*
* @throws \ArithmeticError If the number is not valid, or is not convertible to a BigDecimal.
