Wow George and Nathan, I love that you've used not only your maths learning, but also shown how much you've progressed in your use of ICT.
You imported a very suitable picture and have linked it from the internet, which is tricky to do! I love all the different colour and fontsets that you've used too to add interest to your post, well done!
Great demonstration of your maths learning here too by the way. Your inverses are all spot on!
Great job both of you!
