5MATH WITH DIGITAL CIRCUITS
In the previous chapter we covered logic gates and digital circuits, which enable us to implement logical expressions in hardware. Earlier in this book we defined computers as electronic devices that can be programmed to carry out a set of instructions. In this chapter, I begin to bridge those concepts by showing you how simple logic gates pave the way for the operations a computer executes. We cover a specific operation that all computers are able to perform–addition. First, we go over the basics of addition in binary. Then we use logic gates to build hardware that adds, demonstrating how simple gates work together ...
