:point_right: Your function signature does not match the provided example.
The challenge states that you should create a method that "matches the signature of the MathOperation delegate"
A function signature is defined by the number and type of parameters it takes, and the type of the value it returns.  The MathOperation delegate takes an int parameter, and returns an int value.  But you created Add to take a string array (string[]) and return nothing (void).
Try again with this requirement in mind.
