To clarify, you add all the equations together but multiply the values?

Yes you add all of them up at the end. If you reverse a reaction, it is negative. You multiply/divide H by whatever you manipulate the reaction. Remember that you can do this because enthalpy is a state function!

This is correct thank you for the clarification.
