Combinational logic

Combinational logic is something that we use to make things happen when two or more things happen at the same time. For example, a kind of combinational logic is like a traffic light: when two cars come to an intersection at the same time, they both want to go across. The traffic light says one car can go, and the other has to wait, so that both cars don't try to go at the same time. That's an example of how two things happening at the same time can be controlled by combining them together in a certain way.
