5⋅5, or 5 2 (5 squared), can be shown graphically using a. Each block represents one unit, 1⋅1, and the entire square represents 5⋅5, or the area of the square. In, a square is the result of a by itself.

The verb 'to square' is used to denote this operation. Squaring is the same as the power, and is denoted by a 2; for instance, the square of 3 may be written as 3 2, which is the number 9. In some cases when superscripts are not available, as for instance in or files, the notations x^2 or x.2 may be used in place of x 2. The adjective which corresponds to squaring is. The square of an may also be called a or a perfect square. In, the operation of squaring is often generalized to, other, or values in systems of mathematical values other than the numbers.

For instance, the square of the x + 1 is the ( x+1) 2 = x 2 + 2 x + 1. One of the important properties of squaring, for numbers as well as in many other mathematical systems, is that (for all numbers x), the square of x is the same as the square of its − x.

That is, the square function satisfies the identity x 2 = (− x) 2. This can also be expressed by saying that the squaring function is an. The graph of a has a shape. The squares of numbers make a. The squaring function preserves the order of positive numbers: larger numbers have larger squares. In other words, squaring is a on the interval 0, +∞). On the negative numbers, numbers with greater absolute value have greater squares, so squaring is a monotonically decreasing function on (−∞,0.

Hence, is the (global) of the square function. The square x 2 of a number x is less than x (that is x 2.
