In this activity students will practice adding and subtracting complex numbers. The first four problems are simplifying powers of “i” and the other problems are all adding & subtracting complex numbers. There are also 3 word problems that students have to first translate and then solve involving adding complex numbers.
Students will simplify the expression and then find their answer on the back, crossing off the letter that corresponds to their answer. At the end, the letters that are left over will be the answer to the riddle. This activity is great for self-checking, as students immediately know whether or not they did the problem correctly.
