    Public discussion Created by Marius Sandu

    Boolean Algebra - a much more interesting and relevant topic than some of the Level 2 and Level 3 Mathematics Achievement Standards.

    It may sound geeky but is actually all common sense - useful to our akonga in every aspect of their future life, from understanding robot language algorithms  to decision making, or understanding the terms and conditions of the warranty of their car.

    Most 2-state or cascading 2-state logic problems can be solved with boolean algebra.

    Example 1 - which car warranty would provide wider coverage:

    a) your car warranty covers 100,000 Km or 5 years

                                                    or

    b) your car warranty covers 100,000 Km and 5 years

    Example 2 - use of IF, AND, FALSE, NOT etc. functions in Excel formulas

    i.e. Working out the amount of tax and net pay for someone who earns between $14,000 - $48,000pa - =IF(14000<Gross<48000,14000*0.895+(Gross-14000)*0.825,0) This will return the net pay per year.

    Example 3 - for ax^2+bx+c=0 - IF((b^2-4ac)>=0,REAL,IMAGINARY)
