Numbers (of objects) that can be arranged into a square array are called square numbers. Not a square number: Square arrays must be full if we are to count the number as a square number. Here are 12 pennies arranged in a square, but not a full square array. The number 12 is not a square number.
The square of any positive or negative number is positive, and the square of 0 is 0. Therefore, no negative number can have a real square root. However, it is possible to work with a more inclusive set of numbers, called the complex numbers, that does contain solutions to the square root of a negative number.
