Logic Gates are along the side, while the inputs are along the bottom. Use the bottom buttons to make a series of inputs, then select which logic that you would like to apply to the A&B inputs. Comment what I should make next. :D
[Note]: The NOT gate only takes in the A input. [Note]: Mobile Friendly. [Note]: Comment to learn what they mean! [Note]: If you don't understand the logic, than visit: https://www.youtube.com/watch?v=WII9HWnf3V4
