you got any idea what this means?
Not really, this is completely new to me.
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
DIvision or subtraction then?
addition, not closed division, not closed subtraction, not close since \(-1-1=-2\)
it is closed under multiplication though
Multiplication Subtraction Division all of the above is what I have for answers
hmm the last two, but that is not a choice it is closed under multiplication, not subtraction or division
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?
Its a stupid question. thats what it is lol Which one would you choose?
i guess i would choose "division" but it really says "not closed" right?
if you multiply any two of those you get another one of those for sure
It does say not closed!
so it is closed under multiplication don't choose "all of the above"
ok pick division i guess and write them and tell them it is a mistake on line class?
Yeah! I'll tell them!
Could you help me with one more?
sure i can try
i thought they new better in washington
