An Interface With Multiple Methods

The interface IMathOps declares both Add and Subtract. Complete the MathOps class so Add returns the sum and Subtract returns the difference (a - b). Do NOT write a Main method.

For Add(7, 3) and Subtract(7, 3) the program prints each result on its own line:
10
4

Expected Output:

10
4
