Negative Absolute ValueDate: 6/28/96 at 22:57:17 From: Joan Havey Subject: Negative Absolute Value Dear Dr. Math: My student and I are wondering if -|8| is -8 or 8 We have different opinions on the answer. Thanks! Joan Havey Date: 6/30/96 at 15:55:46 From: Doctor Paul Subject: Re: Negative Absolute Value I say it's -8. Here's why: The minus sign acts after the absolute value is taken. |8| is 8. Then put a - sign in front of the 8 and you get -8. Note that -|-8| is -8 too. This is because the abs. value of -8 is 8 and then the minus sign goes out front. -Doctor Paul, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
