Calculation history helps you review earlier steps, copy results, keep important values and continue without retyping the same numbers. When a problem is on paper, a bill, a worksheet or a screen, scan it with the camera and solve math from a photo. Unit and currency conversion make the app useful for school, shopping, work estimates, travel planning and comparing prices across currencies.
