Ozzie's Mother bought an assortment of greeting cards while she was at the bookstore. She bought twice as many birthday cards as
anniversary cards. She bought 2 fewer anniversary cards than general greetings cards, but 2 more anniversary cards than get well cards. If she bought 2 get well cards, how many cards did she buy in all? Brainlist
An imaginary number " i " is the squared root of -1, so whenever you square i it's like squaring a squared root. The squared root would cancel and you would be left with just the number under it, that is, the -1. i ^ 2 = -1
