That's because you are multiplying it by itself. So "two, squared' means the same as 'two times two', and 'three, squared' means the same as 'three times three'.
Multiplying a number by itself is exactly the same process of finding the area of a square who's dimensions are the number in question. Therefore multiplying a number by itself is known as squaring. For the same reason of raising a number to the third power is known as cubing. (Because its the same process you would use to find the volume of a cube.)

What is it called when raising a number to the second power?
Taking a number to the second power is known as "squaring" the number.
What is 7 to the 2 power?
49."To the second power" means that the number is multiplied by itself once.We also refer to this as "squaring" or that a number has been "squared".7 * 7 = 49.
How do you write 20 squared?
To write powers of a number you write the number, followed by the number of the power in superscript. For example, a number to the second power is x2, a number to the third power is x3 and so on. Squaring is taking a number to the second power. Thus 20 squared is 202, which equals 400.
Why is a quadratic function called a quadratic function?
A quadratic function is a second degree polynomial, that is, is involves something raised to the power of 2, also know as squaring. Quadratus is Latin for square. Hence Quadratic.
What is the number by which you are dividing?
In a division sum, for example, 12 / 6 = 2, the first number in the sum is called the dividend. The second number is called the divisor, and the third number is the quotient. In this instance, it is the second number you are finding.
