Figure 5

You’ve nearly made it through the course, and you’ve examined how you can present numbers as fractions or percentages and you’ve also considered when and why you should round numbers.

Hopefully you enjoyed the video on negative numbers, and perhaps it gave you some ideas on where to go (or where to avoid) next time you start planning a holiday!

Next week you’ll be looking at averages, correlation and interpreting graphs before taking the end-of-course quiz to see what you’ve learned.
