#004 #dailyui Calculator

The calculator ui for a standard calculation. The idea behind the ui was the change the number layout to the easier version of the dialpad. I don't understand why the industry hasn't updated the design until now, and tried doing a little research on it. I understand that user familiarity is for the old version, but with a more effective layout, wouldn't it be easier for the later generations instead of teaching them the old way every single time..? Just a thought.
Also, the calculation used is displayed for visual reference to the user.
