Homework Statement
Build a circuit that either adds or multiplies two 4-bit numbers based on a control input C(C is 1 add, C is zero multiply). Numbers are positive and negative so use two's complement. You can use muxes, Full Adder Circuits, and logic gates

Multiplier circuit=
Adder Circuit:
The Attempt at a Solution
So, I have built both the Full Adder(for the addition part) and the multiplier. However, I don't know how to use the muxes to get the input switching if control is 0 and 1. Since the mux only has one output, I don't understand how to connect the two circuits together. Any help is much appreciated!
