-# Description
-
-We are launching a deep space exploration rocket and we need a way to make sure the navigation system stays on target.
-
-The first step in our coordinate calculation involves taking a number as input and finding another number which multiplied by itself will equal our input number, or in other words, finding the square root of our input number.
-
-Because the journey will be very long, we had to make our rocket’s onboard computer very power efficient so it wouldn’t drain the batteries.
-Unfortunately that means that we can’t rely on fancy math libraries and functions, as they would take more power.
-Instead we want to calculate or approximate the square root directly.
+# Instructions
 
 Your task is to implement a calculation of the square root of a given number.
