Squaring a number means that you are multiplying a number by that same number. For example, if you multiply 2 by 2, then you can say you are "squaring" 2 in order to get 4. 4 is considered a "perfect square" because it is the product of a squared number.
To square a number, you must multiply it by itself. For example, 5 squared is 25, because 5 x 5 = 25. To give another example, 10 squared is 100, because 10 x 10 = 100.
To square a number, simply multiply the number by itself. This action results in the area of the square created with a side equal to the number that has been squared. This is one of the oldest mathematical computations known to man because its uses are so numerous and so basic.
