Excel 2007 : Help needed to write a subtraction formula

Thanks again!

The anwer will not always be betwee 1 - 10. The numbers I'm using in the calculation are currency prices and I'm trying to calculate the difference between the two in "pips". Pips are the unit of measure in currency trading. e.g. 125.145 - 120.00 = 514.5 pips

Any suggestions?
