Calculator: How would you display the total when the + or - button is pressed instead of the = sign? The proposed scenario would look like this: Press '6' (display 6). Press '+ 7' (display 7) press '+' (display 13). This would eliminate the need for the = button. Note: on the current sample calculator app, if you press '6 + 7+' and then decide to press the = button, it clears out rather than giving the total.
