+# Instructions
+
+Given a natural radicand, return its square root.
+
+Note that the term "radicand" refers to the number for which the root is to be determined.
+That is, it is the number under the root symbol.
+
+Check out the Wikipedia pages on [square root][square-root] and [methods of computing square roots][computing-square-roots].
+
+Recall also that natural numbers are positive real whole numbers (i.e. 1, 2, 3 and up).
