How Do You Calculate Square Root?

In summary, a square root is a number that, when multiplied by itself, gives the original number. It is represented by the symbol √ and can be calculated using various methods. Finding the square root of a number is different from squaring a number, which involves multiplying the number by itself. The square root of a negative number is not a real number, as a negative number multiplied by itself always results in a positive number.
