put a six digit number into the display. you must change each of the six digits to zero in as few turns as possible. on each turn you can use only one number key, the zero key as often as you like and the + key.
Example:
start number: key presses: display:
123,456 +4 123,480
+20 123,500
+500 124,000
+6,000 130,000
+70,000 200,000
+800,000 1,000,000
variation:
use a decimal number example 451.326
on each turn you can only use one number key, the zero key as often as you like and the decimal point and the - key. shoot down the digits to zero (or make them disappear) in numerical order 1,2,3,4,5,6...
