We input the 8-bit numbers with 8 switches (representing high or low) per number to represent each bit.

For example, using our switches, we add 10101010 and 00001110 for a sum of 010110000. We then need to display each one of those numbers with a seven segment display. We have no idea how to (efficiently) do this. Are there any chips or demuxes or anything that we could use to convert the 8 and 9 bit binary into seven segment displays? We would need 3 displays per number, since it can be up to three digits in base10 form.
