I need to make a binary adder ( not actually sure if this is 8 bits or 16 bits)

There will be 2 8-bit inputs (each one represents 2 digits in binary)

The output will be 8 LED's displaying the sum (again in binary)

There will be limitations, but this is what I need to do.

The only thing i can find is 4 bit full adders. I am not sure how to connect them or how many I need.

01010100 01101000 01100001 01101110 01101011 00100000 01011001 01101111 01110101 00100001
