It follows from the closure of integers under addition and multiplication.Any rational number can be expressed as a ratio of two integers, where the second is not zero. So two rational numbers may be expressed as p/q and r/s.A common multiple of their denominators is qs. So the numbers could also have been expressed as ps/qs and qr/qs.Both these have the same denominator so their sum is (ps + qr)/qs.Now, because the set of integers is closed under multiplication, ps, qr and qs are integers and because the set of integers is closed under addition, ps + qr is an integer.Thus the sum has been expressed as a ratio of two integers, ps + qr, and qs and so it is a rational number.
Suppose x and y are two rational numbers. Therefore x = p/q and y = r/s where p, q, r and s are integers and q and s are not zero.Then x - y = p/q - r/s = ps/qs - qr/qs = (ps - qr)/qsBy the closure of the set of integers under multiplication, ps, qr and qs are all integers,by the closure of the set of integers under subtraction, (ps - qr) is an integer,and by the multiplicative properties of 0, qs is non zero.Therefore (ps - qr)/qs satisfies the requirements of a rational number.
Yes 20 is an ABUNDANT number because 1+2+4+5+10=22 and that is more than 20. PS how to find and ABUNDANT number is to add up all its factors. :)

no this school is not real it is a cartoon tv show
It came from a number called googol. This is 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. Basically, one with 100 zeros after it. PS this is not a joke, it is a real number. Google is named on this number, because of the fact that you can find so much stuff.

yes clairville is a real school. it is in bramton Ontario on gallcucci road
it based on a fake story ps shark attack was not real it fake
plus
Real Steel is a download and not for the PS2
PS in the measurement of space typically stands for "parking space" or can refer to "parcel square footage" in the context of real estate.
It says it is real on the episode of Victorious "The Wood." But when you type in on Google "TheSlap.com" it only comes up "Nickelodeon" so it is NOT real. PS. I wish it was real hahaha
Yes. In every call of duty game the missions are based on real ones. The characters are real and everything that happens is real. PS. Weaver was NOT real!
Oh, dude, PS on the periodic table stands for PostScript. Nah, just kidding! It actually stands for Plumbum, which is the Latin word for lead. So, like, if you were hoping for some cool abbreviation, sorry to disappoint, but hey, at least now you know it's not a secret message from chemists trying to be sneaky.
