*sigh* It adds numbers using a combination of XORs and the carry line.
You can create lines that, when powered will force certain circuits in the ALU to remain on, such as the carry line (flooding or cutting it) as well as adding things to the front, like inverters. An ALU is simply an adder with fancy circuits around it that will turn parts of it on and off to the point where it can be used for other things (OR, NAND, XOR, etc)
