How do you express Celsius and convert it to Fahrenheit?

Instructions: Let's add some code to the body of the function. Get rid of the existing return statement that's in there and in this task we're going to write out code to take a Celcius temperature value passed in and convert it to Fahrenheit.

To convert from Celcius to Fahrenheit - multiply the value by 9, divide the resulting value by 5 and then add 32.

Once you have the Fahrenheit value, return it from the function.

How do you express Celsius and convert it to Fahrenheit?
