So, I have a question from a test I took and got a 80% on it, apparently I missed this question For which operations is the set {0, 1} closed? A. Multiplication B. Division C. Addition D. Subtraction I picked A but the correct answers were A and B Why division? You can't divided 0 by 0? right?

    well technically 0 divided by 0 is 0...

    But, in the lesson they specifically said you can't do that.

    @mrqueest 0 / 0 is NOT 0 For all values of \(a,b,c\), if \[a/b = c\] then \[c*b =a\] Does that work for \(a/0=0\)? \[3/0 = 0\]means that \[0*0 = 3\]but it isn't.

    My guess is that division was included with the understanding that division by 0 is excluded because it gives an undefined result.
