Final words
This is the first video in the measurement, scale and similarity section of the Year 11 General Maths (Units 1 and 2 ) course for VCE. Part of a much larger section of work, this video looks to introduce and teach you the very important concepts behind rounding to decimal places, rounding to significant figures and how to use scientific notation to write really large or small numbers in a simpler form. I used humour and plain speaking to ensure that everyone who watches the videos understands the work.
