It is represented by a superscript number 2 and placed in the upper right corner of the multiplicand. For example, the square of 2 is 22, which is equal to 2 times 2, and the result is 4. Similarly, the square of 3 is expressed as 32, which is equal to 3 times 3, and the result is 9. Square is widely used in mathematics, such as calculating area, volume and distance.
In addition, the square can also represent higher power. For example, a cube refers to a numerical value multiplied by itself twice, which is represented by the superscript number 3. Therefore, square is an important symbol in mathematics, which is used to represent the operation of multiplying a numerical value by itself.
