nOkialpha Posted April 6, 2019 Share Posted April 6, 2019 For better productivity, this Fractions Calculator implements innovative User Interface which does not contain "=" operator. Just enter the first and second Fractions into left and right upper boxes (underscored) and hit the arithmetic operator Button ("+", "-", "x" or "÷"), thus saving the click. The result appears in the multi-line display beneath input boxes. Scroll the display viewport up and down to see the calculation history; swipe to left or right to swap the input boxes content. https://play.google.com/store/apps/details?id=biz.infosoft.fractal Link to comment Share on other sites More sharing options...
