Robot Math

An educational arithmetic drill. On the title you set it up: addition or subtraction, 2 to 6 digits, carrying or borrowing allowed or not, and 5 to 9 problems. Each problem is set out in columns on an LED read-out panel. Dial your answer digit by digit, starting from the units column and working left as on paper, then press the button to check it. You have three tries and four minutes for each problem. A right answer sends the robot walking along the conveyor belt and back, and scores more for longer problems and fewer misses. A problem missed three times, or timed out, shows its answer and costs the robot one of its three batteries; losing all three ends the game. Solve every problem to win.

Controls: Use either controller. During play, push up and down to dial the digit under the cursor, left and right to move the cursor, and press either button to check the answer. On the title, up and down choose a line, left and right set it, and a button starts.
