Square root is a reverse calculation of square. quare root is often difficult to calculate.

Suppose a number called *a*, you can think of a number multiplied by the same number *a*.
The number is, *a* x *a*, often notated as *a ^{2}*.

We say *a ^{2}* is a square of

*a*.

Now we consider the reverse calculation of square. That is, when a number *b* is given, to find a number *c* where *b = c ^{2}*.
We notate as

*√b = c*.

While calculating a square is relatively easy, calculating a squareroot is often a labor.

Here is a form for calculating a squareroot.

* Please do not enter a negative number. The formula above cannot handle the negative number.

* Mathematically, a number has two square roots, one is plus and the other is minus. On the formula above, it shows only the plus one.
