Skip to 0 minutes and 3 secondsHello, and welcome to Week 3 of the course. Last week, you learned all about combining transistors to make logic gates. This week, we're going to look at the core function of a computer-- performing calculations on binary numbers. And you're going to learn how to do some of these calculations yourself.
Welcome to Week 3
Welcome to Week 3 of How Computers Work.
So far you’ve learned all about how computers use logic gates to represent 1s and 0s, and how some arrangements of logic gates can be used to do some simple processing to provide useful output. You’ve also had a look at the binary counting system, and so you should hopefully have realised that logic gates can be used to store and process binary numbers.
This week we’re going to look at the core function of a computer: performing calculations on binary numbers. You’ll learn how to add and multiply binary numbers, and how logic circuits can be used to perform the same operations.
