Date: 3/19/96 at 20:18:54 From: Doctor Patrick Subject: Re: Suggestion Box Hi Mike. Adding a negative number is exactly the same as subtracting a positive number. In your example, 123 + (-43) is the same as 123 - 43. Think of it this way - If you had $123 and I gave you a bill for $43, how much would you have? You would have to subtract the $43 from the $123 to get your answer - you would be adding a -$43 to what you had, or $80. Hope this helps, -Doctor Patrick, The Math Forum
