When the square root of a number is squared, the result is the original number. The square root function is the inverse of the squaring function just as subtraction is the inverse of addition. To undo squaring, we take the square root. The square root could be positive or negative because multiplying two negative numbers gives a positive number. The square root obtained using a calculator is the principal square root. The symbol is called a radical , the term under the symbol is called the radicand , and the entire expression is called a radical expression.

Square Roots An exercise in multiplication experimentation. As you know, the area of a square is found by multiplying its length times its width. EX: Let's say the area of this square is 49 square centimeters. How long is it on one side?

Our square root calculator estimates the square root of any positive number you want. Just enter the chosen number and read the results. Everything is calculated quickly and automatically! With this tool, you can also estimate the square of the desired number just enter the value into the second field which may be a great help in finding perfect squares from the square root formula. Are you struggling with the basic arithmetic operations: adding square roots, subtracting square roots, multiplying square roots or dividing square roots? Not any more!
