===============================

In this session we will build a device for adding and subtracting (unsigned)
integers.

In __Section 2.1__ we will introduce the so called multiplexer. How to subtract
integers (by re-using the adder) is covers in __Section 2.2__. Finally we will
combine addition and subtraction in a single device in __Section 2.3__.
