Challenge help

I can figure out what to write for this challenge, I've tried several different things but I can't seem to get it right. It asks you to simply write out the implementation for a function called addTwo, which adds the sum of two float numbers. I need help

Great thanks. I tried that, but had a semicolon after the parameters, thus the error. Thanks.
