Lin says, "When you add or multiply two complex numbers, you will always get an answer you can write in a+bi form." Noah says, "I don't think so. Here are some exceptions I found:" (7+2i) + (3-2i) = 10 (2+2i)(2+2i) = 8i 1. Check Noah's arithmetic. Is it correct? 2. Can Noah's answers be written in the form a, where b and are real numbers? Explain or show your reasoning.
