On the Subject of Green Arrows

What's the point?

On the module are 4 directional buttons, and a display screen in the middle.

If the buttons are not Green, you're looking at a different module.

On the screen is a random number somewhere between 00 and 99. Look at the table below to find the correct button to press. Use the 10s digit as the column, and the 1s digit as the row. After each correct presses, the number will change. Keep repeating the process, and the module will be disarmed after 7 consecutive correct presses. Pressing the wrong button will register a strike and reset your streak.
