Andrew,

Can you clarify which part you are having trouble with? You need to define a function which takes two parameters (of type float) and returns the sum of those parameters (also a float). The basic syntax for defining a function is as follows:

(return_type)functionName(type parameter_one, type parameter_two)
{
   //add the two numbers together and return the result
}

i have tried this several times, looked back at the function tutorial, and still cannot understand what exactly I am doing wrong.

They are asking you to return a float as a result. In the tutorial they return integers. What you have to do is this:

float addTwo(float a, float b){
return a+b;
}
