Design a circuit to add two 2-bit numbers using a 7483 4-bit adder. Use 2 switches on the designer to input 1 value and 2 other switches to input the other value.

1)The 7483 adds 2 4-bit values. What must be done with the unused inputs?
2)What should be done with the carry input?
3)How many outputs from the adder must be connected to the LEDs to see all the possible outputs?

Produce a logic diagram for this circuit. Show the adder as a single functional unit. It has nine inputs--two 4-bit values and a carry input--and five outputs--the four sum bits and the carry out.
