1.2 Talking and writing mathematics

One way of testing whether or not you are conforming to the first guideline, is to read your solutions through aloud. Speaking aloud involves you in translating every symbol on the page into its verbal equivalent. If you find yourself needing to say more than is written on the page, you may need to expand your written account. To give you practice at this and at assessing the quality of some written mathematics, work through the animation below. The actual mathematics used is not important; just concentrate on the style of its presentation.

Working through the following animation should take you about forty minutes. The relevant frames are shown with the appropriate extract and you will need to answer using pen and paper. After each extract you will need to click on the play button to hear the next audio.
