Even + Even = EvenDate: 11/06/2001 at 15:33:39 From: Courtney Subject: Even + even = even Do you know how to prove that an even number + an even number = an even number? Date: 11/06/2001 at 15:36:54 From: Doctor Paul Subject: Re: Even + even = even An even number is a multiple of two. Show that the sum of two multiples of two is again a multiple of two: if x and y are even numbers, then x = 2*p and y = 2*q for some integers p and q. Then x + y = 2p + 2q = 2(p+q) 2*(p+q) is a multiple of two as well, so x+y is even. - Doctor Paul, The Math Forum http://mathforum.org/dr.math/ |
