    that is what thought closed under addition for example would mean if you add any two of those you get another one of those

    that is not true, since \(1+1=2\) and \(2\) is not in your set

    it also not closed under multiplication since \(1\div 0\) is not a number

    addition, not closed division, not closed subtraction, not close since \(-1-1=-2\)

    certainly it is not closed under division because you cannot ever divide by zero but it is also not closed under subtraction what is this, some FLVS question?
