i have no idea how to write this code at all

writing a function usually looks something like this

returnType functionName(dataType arguementOne, dataType argumentTwo) {

    //do whatever you need to do
    return something;
}

the question gives you the return type, the function name, the datatype and number of arguments and tells you what you need to do inside the body of the function (return a float thats the sum of two arguments).

Try watching the video one more time.

It should be something like this:

<return type> <name of function> (<datatype> argument1, <datatype> argument2){
   return (argument1 + argument2);
}

I'm having trouble with this challenge as well. I typed: float addTwo(float a, float b) { return (a + b); } //and it isn't working.

Thats correct but there shouldnt be no parentheses in the return... so { return a + b; } also theres something wrong with the challenege ATM

ok thanks

Some recent changes to challenge broke it. Sorry about the inconvenience but it should work now.
