**Could copy and paste your square root code**

With a few changes, you
could copy your original code that computes the square root and insert it as *
in-line code* at each location in your program where you need to calculate
the square root of a number.

**Is there a better way?**

After doing this a few times, you might start asking yourself if there is a better way.

The answer is *"yes, there is a better
way."*
