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.
For any positive number there are two numbers you can square to get that number. For example there are two numbers you can square to get 9: 3 and -3. In general, for some positive number we will call x, the two numbers you can square to get x are called the square roots of x. One is the positive square root and the other is called the negative square root. The positive square root of 9 is 3 and the negative square root of 9 is -3. is the negative square root. is a reference to both square roots! (Note: The zero in front does not belong there! I myself have used the phrase square roots must be positive.
