Miracrown (miracrown):

Do you understand the concept of a closed set?

OpenStudy (anonymous):

WILL GIVE MEDAL AND FAN

Miracrown (miracrown):

To clarify it a little, a closed set of numbers is that in which making an operation between those numbers..we get a result that is also on that set of numbers.

Miracrown (miracrown):

So which operations would you say make this set closed'

OpenStudy (anonymous):

multiplication and division?

OpenStudy (anonymous):

@Miracrown

OpenStudy (anonymous):

you there? @Miracrown

Miracrown (miracrown):

Yes, for multiplication if we make 0*1 or 1*0 we get 0... and 0 is in the set For division, if you make 0/1 we get 0. But we can't make 1/0 To be a possible one we always have to be able to apply the operation in both ways 0 by 1 and 1 by 0 I mean

Miracrown (miracrown):

So, division is not one of them because of what i just said if we make 1/0 we get an absurd..thats why we cant say its a possible answer

OpenStudy (anonymous):

ok so is it just multiplication?

Miracrown (miracrown):

Its multiplication and addition also, because if we add 0+1 we get 1... and if we add 1+0 we also get 1 and both results are in the set.
