Why is square 1 negative?

Originally Answered: Why does I * I = -1? Is the same as -1, as the root and square cancel. Its because i is defined as the square root of negative one, and when you multiply i by itself or in other words, square i, you multiply two square roots to get the square. The square in this case would be -1.
