When I was at school in the UK the Casio calculator reigned supreme. Luckily there is this rather nice Android App called RealCalc which emulates the kind of caclulator I used to use at school quite well! https://play.google.com/store/apps/details?id=uk.co.nickfines.RealCalc&hl=en_GB https://play.google.com/store/apps/details?id=uk.co.nickfine... I spent 100s of hours using that calculator so having a exact replica on my phone is very helpful. My kids use yet another different Casio calculator which continually frustrates me with its desire to represent everything as a fraction!
