## What will I learn?

This puzzle makes you split a string into substrings, replace a character of a string and convert it into floats. You also have to convert degrees into radians and use mathematical operations like square root or cosinus.

Finally you have to apply multiple computations (addition, multiplication...) on floating numbers.
