What is the bipolar input and bipolar output truth table of ANDNOT function

I forgot to clarify I know that. I am confused because table of mine and book are different. I just want a simple ANDNOT truth table. Can you provide that? or tell which one is correct?

Why does the book answer with 3 columns and you answer with 4 columns?

First, here is what you posted (we prefer not to have to click through to see images):

There are several questions here. First, I am not familiar with the name "ANDNOT"; it would be helpful to show the definition you were given. But the book's table (as you wrote it) is for "x1 AND NOT x2", that is, [imath]x_1\wedge\neg x_2[/imath], which is what I would expect it to mean. Your table is for "NOT(x1 AND x2)", that is, [imath]\neg(x_1\wedge x_2)[/imath]. I would call the latter "NAND".

Second, your two handwritten tables are not for the bipolar form. Why?

Third, Table 13, which is in bipolar form, is also for "x1 AND NOT x2". It is true only when x1 is true and x2 is not.

Does any of this help?
