Introduction

The binary system uses 10 digits (0 to 9) to write all numbers. However, this is not the only existing system. For example, we count hours, minutes and seconds using the sexagesimal system (60 digits). In the case of computers, they communicate with the world using a binary system (which uses 2 digits). In this activity, you will learn how to write decimal numbers in the binary system. Get your mental calculation abilities ready!
