4.8 Optional Activities

Extensions and Further Exploration

In this section, we will try to extend our knowledge that was discussed throughout the unit. If you find a problem difficult, read back over it, briefly set it aside and revisit it later, or discuss it with a friend. But don’t panic; just keep going!

The next section is optional and gives you the opportunity to practice all the skills you've already learnt in this unit, and begin to think about how you might apply them in your everyday life. If you choose to do it, this section will take you about an hour and a half more.

Let’s begin by taking a look at how numbers used in codes affect our daily lives!
