Image Calculator

Image Calculator allows users to draw numbers instead of pushing virtual buttons.
The app is suitable for any user that would like to try this alternative input method.


● Do basic calculations
● Draw the numbers (no number pad)
● Fast input and automatic results


The app will detect 12 symbols when an image is drawn by the user :


0 1 2 3 4 5 6 7 8 9 ( )


Please ensure that the symbols are drawn correctly (more or less).
The symbols have to be drawn, one at a time, in one continuous interaction.
The symbols must also be drawn in the "standard" way (e.g. drawing "2" starting at the top).
Drawing large and well-formed images will result in near-perfect recognition.


Button guide :
C -> clear all input
Cycle -> reuse answer
% -> do percentage calculations ( e.g. 125 - 20% will return 100 )
Back -> delete the last symbol entered
+-/x -> arithmetic operators
. -> decimal point
