What happens if you square a negative number
When you multiply a negative number to a positive number, your answer is a negative number. The fact that the product of two negatives is a positive is therefore related to the fact that the inverse of the inverse of a positive number is that positive number back again. When you have two negative signs, one turns over, and they add together to make a positive. If you have a positive and a negative, there is one dash left over, and the answer is negative.
Subtracting a negative number is the same as adding a positive number — that is, go up on the number line. This rule works regardless of whether you start with a positive number or a negative number.
When adding positive numbers, count to the right. When subtracting positive numbers, count to the left. When subtracting negative numbers, count to the right.

When I square a negative number i. No number, positive or negative, can result in a negative square.

If you square a positive, you multiply a positive by a positive and get a positive.
If you square 0 , get 0. Therefore, in no case is the answer negative. It is harder to explain why a negative times a negative is positive.
The square roots of any positive real number are a positive and a negative real number. The square roots of any negative real number are a positive and a negative imaginary number. The square roots of any imaginary number or any complex number are two complex numbers. The answer is an imaginary number, because of the negative under the square root. The same number multiplied together will always be a positive number.
For example, if you square negative one, the answer is positive one, because a negative times a negative is a positive. Because a square root undoes a square, there is no solution to the square root of a negative number.
That's why your calculator could not compute this problem. However, there is a way to solve these types of problems by using imaginary numbers. The answer is 13i, where i is the square root of negative one.
