How to simplify the two non-as follows

F=AB'+A'B (and or form) → twice negated →F=((AB'+A'B)')' This is right and wrong-and non-form.

F= ((AB'+A'B)')' =((A'+B)(A+B'))' This is OR-and-NO.

In fact, remember that AND is multiplication, OR is addition, NOT is negation, AND OR comes before OR, and so on.

(

1) AND gate is also called AND circuit, logical product circuit and logical AND circuit. It is a basic logic gate circuit that performs AND operation. There are multiple inputs and one output.

When all inputs are at the same time high (logic 1), the output is high, otherwise the output is low (logic 0). Logical expression: F=AB.
