Introduction

Our decimal number system we use is based on the fact that we humans are born with ten fingers (including thumbs!). But computers naturally speak in multiples of 2, like 2 (binary), 8 (octal), and 16 (hexadecimal).

In this lesson, we are going to explore how computers think in octal and how it relates to decimal and binary.
