## On the Subject of The Red Button

This is a button. It is red.

The module contains a red button with a logic gate written on it and a screen consisting of red and green 0's and 1's.

The 0's represent "false", and the 1's represent "true". The numbers in the top row pair with the numbers below them in the bottom row.

Red numbers represent a false statement, and green numbers represent a true statement. These statements must be determined to be true or false based on the logic gate written on the button.

To toggle a pair of numbers to be true or false, hold the button down over the timer tick in which the seconds digit is equal to the position in the rows. A cyan LED will light up to signify your position in the rows.

To submit the module, tap the button.
