1. Lab 5 A 3-bit Adder/Subtractor for 2's Complement Binary Numbers
2. The purpose of this lab was to use switches as the 3-bit
inputs and use leds to show the binary results of the 3-bit
adder and subtractor using 2's complement. Similarly, to implement the
3-bit inputs to display the number result of the seven segment display
and display negative values if a negative result is produced by the
adder subtractor.

Discussion
The lab was challenging. The verilog code was hard to grasp at first
especially for the seven segement display. Splitting up the code
allowed one to get a better feel for the code over all and allowed for
easier debugging of the circuit. Passing in the values for the seven
segement took some time to figure out as well as the counter for the
display module.
