[Year 12 SofDev] More fun

[Dr Paul Chandler]

... To which we could add a few more:

- conversion of a number in one base to any other (using the 'division
method')
- digit-by-digit addition
- digit-by-digit subtraction using decomposition method 
- digit-by-digit subtraction using equal additions method
- demonstration of long division
- derivation of square roots (manual method, similar to long division)

Subject: [Year 12 SofDev] More fun - and a fix

Fixed Fun #6 - given a price including 10% GST, give the ex-tax price
and the tax component, e.g. $11 inc = $10 ex + $1 GST.

New Fun #10 - given an integer number of dollars, calculate what notes
or coins need to be given as change from $100.  e.g. $67 = 1 x $20, 1 x
$10, 1 x $2, 1 x $1.
