**dev**, Tuesday, January 6, 2009 at 12:01amThis sounds dumb but do I take

1000-231.05 or 231.05- 1000

If I do it on a calculator I get 768.95, if I set it up with 231.05 on top and the 1000 on the bottom I get 221.05. Something doesn't seem right.

1000-231.05

**DrBob222**, Tuesday, January 6, 2009 at 12:44amIn case you've not used the google calculator, the 1000 goes on top and the 231.05 goes on the bottom BECAUSE you have 1000 miles total and you have already run 231.05 so 1000 - 231.05 is what you have left to run.

If I do this on my calculator, I get

1000-231.05 = 768.95

If I subtract 231.05-1000 I get -768.95 so you must have punched the wrong numbers when you did it. In the second example I have done, the negative sign tells you that you DON'T have negative miles to run. Right?
