I am currently taking up ENGLONE. One topic that is on my mind right now is about logic operations. Therefore, I will discuss some basics about logic operations.
Binary variables and logic operations compose the binary logic. Binary variables are letters of the alphabet such as A, B, C, x, y, and z whose values can only be 1 and 0. The three basic logical operations are AND, OR, and NOT.
The AND operation is represented by a dot or no operator sign at all. Examples are x.y=z or xy=z. This is read as “x AND y is equal to z.” This logical operation means that z=1 if and only if x=1 and y=1; otherwise z=0.
The OR operation is represented by a plus sign. An example is x+y=z. It is read as “x or y is equal to z.” This logical operation means that z=1 if x=1 or if y=1 or both x and y is 1. If both x and y is 0, z=0.
The NOT operation is represented by a prime or an over bar. An example is x’=z or x (place a line over x) = z. This is read as “NOT x is equal to z.” It means that z=0 if x=1 or z=1 if z=0. This operation is also referred to as the “complement operation” since it changes 1 to 0 and 0 to 1.

hmm...very similar to that symbolic logic/ analytical philo subject i took up back in college. interesting.
btw, doesnt this symbol -->! mean "not", too?
lastly, documentation of reference (?) please. thanks.
I think ->! symbol is also for not. If I am not mistaken, we used that in our programming class. I have my source at the bottom but I am still in the process of learning on how to increase the line spaces.. :)
Ate beryl, I like yor topic. Good choice! Ate beryl, please help me put the names of or classmates in my profile.. I don't know how.
thanks a bunch!
