I don't get it. It's supposed to be a clever calculator, modelled on the Chancellor of the Exchequor himself (now PM), but . . . . it gets even the simplest sums wrong!
What's more confusing is that, even though it's supposed to be able to calculate numbers correctly, it then gets it wrong AND helpfully points out where the Chancellor (now PM) has made huge boo-boos and rip-offs of the electorate.
