Dear Experts,
How can I get the real figure if I have the following message?
Negative times are displayed a ###########.
Actually I got the above massage from the below formula.
=2:49 - 3:17, (hh:mm format)
Thanks.

This is because it is running over midnight.

Try

=MOD(A2-B2,1)

You can overcome that by using the 1904 date/time system, but at a price.
ToolsOptionsCalculation tab, check 1904 date system
Note that all dates in your workbook will change.

You can change the date system to 1904 system BUT all dates in your w/book
will be out by 4 years. (Tools=Options==Calculation)

Or convert to decimal times (multiply by 24) and format cells as general or
number.

Multiply result of subtraction by 60 to get results in minutes.

Omar,
You have certainly these hh:mm's in appropriate cells, say A1 and A2. For
obtaining allways the meaningful result (within 24 hours, of course) use
conditionally

=IF(A1<A2;1+A1-A2;A1-A2)

- it "borrows" a necessary day to the calculation.
