Addition Property of InequalitiesDate: 8/29/96 at 20:59:13 From: Anonymous Subject: Addition Property of Inequalities If x>y, then x+z __?__ y+z Date: 8/29/96 at 22:23:49 From: Doctor Jodi Subject: Re: Addition Property of Inequalities Hi there! Let's look at this problem using a number instead of z. Then I think it will be easier. We know that x > y. If we add any number to x, a the same number to y, what will happen? x + 3 > y + 3 x + 0 > y + 0 x + (-8) > y + (-8) We can add positive or negative numbers or zero to each side without changing the inequality. Does that make sense? Write back if you need more help! -Doctor Jodi, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
