Only in Geebung Does Two Plus One Equal Three

Now I have to confess that I went to primary school in the lower working class borough of Geebung, which means like other kids from the mean streets school I learned at an early age to fight and run and punt and play footy and drink and smoke and stand up to bullies and  give blokes who hit women a bad hiding and all that sort of important stuff, but maths was never really a focus.
