If you take the square root of a number and multiply it by itself
you get the number back.  For example, 2 is the square root of 4
because 2*2 = 4.  Similarly, 3 is the square root of 9 because
3*3 = 9.

Not all numbers have nice neat square roots.  The square root of
2 is about 1.41421356237309504880... (The three dots mean
that the number just keeps on going without stopping.)
