full_question: This number is related to Euler’s identity, and is used as a “sentinel value” in software development to show that a variable contains no useful information. This number is used in programming languages to index the last or second to last item of an array, depending on whether that number was 1 or 0.* Multiplying a number by this number is equivalent to changing its sign, which is proved by using the distributive law. For 10 points, name this number, which is the additive inverse of 1.
