# 5 Summary

Congratulations for making it to the end of another week! You have again covered a lot of ground but hopefully you will feel more confident after completing this week’s quiz that you can now tackle scientific notation and related calculations, as well as understand some of the subtleties of roots. There was a lot to take in, but remember that you can always look back at your notes to remind you of any rules or ideas if you need to. Next week will cover shapes and how to calculate basic quantities for these, so this is back to maths that is easier to relate to the world around us. See you there!

You should now be able to:

- understand and use scientific notation
- perform calculations with numbers written in scientific notation
- understand and calculate square roots of a number.

You can now go to Week 6.
