Mathpig just learnt this from a young Mathematician age 9.
It is a great way to do maths because you are thinking ‘Mmmm! How can I work these numbers.’
Getting maths students to think about what they are doing is so much better than just having them guess ‘ Arrrr! Whatever. Click B.’

This will be very useful later when it comes to a similar method used to simplify long division:
MATHS IN THE REAL WORLD
which is everywhere!!!!
Economists may not set out to mislead the public, but they do produce graphs that can easily be misread. Here is a graph from AMP (again) published in THE AUSTRALIAN on 29/7/09 (p12 . Wealth supplement.).
Have a look at the graph. What’s wrong with it?????????????
Firstly, you cannot invest money in 1928. To be relevant to you, start looking at the graph when you first had money to invest. 1999? 2008?
Secondly, look at the Y-axis scale. This is NOT a LINEAR graph. This is a logarithmic scale. That little blip drop in Australian Shares value at the end is worth $331,375!!!!! If you had $1,000,000 (Just retired, for instance) and put your money in shares in October 2007 that is how much money you would have LOST.
Here is a liner graph showing clearly (and more honestly) the drop in the All Ordinaries Index in the Australian Share Market during the GFC. The graph came from Sharewatch.
