Match the example display (number display) with the left ones, there are 5 switches (logic sources). Change the left using the 4 switches and the 5th ones lets you change the example display without the 4 switches. You can change it using the 2 pushbuttons. You can change the left using A (1st switch) B (2nd switch) C (3rd switch) D (4th switch). Don't cheat, Good luck! Any questions? Tell me in the comments!
