Thanks for explanation, I was sure this is logic operation, my bad.

But arithmetic combinator shouldn`t compare value of signals at all, it`s decider combinator`s functional. Arithmetic combinator with "AND" operation should check only input`s signal exist, that`s point. Otherwise, you have two different entities with identical functional. 1st screenshot -...

Operation "AND" in arithmetic combinator compare both signals and its values, but it`s looks like it should check only exist of signals, because functional of checking signal and its value already exist in decider combinator. I mean when we send for example "A10" and "B1&quo...
