I am trying to add negative time, hours and minutes (-1:32) to positive time (0:34). These are totals for hours worked above 40 hours. I have changed to the 1904 date system but my formulas aren't working. I'm not very familiar with Excel. I'm trying the formula =SUM(A1+A2) with A1 and A2 being in time format. I have found many threads about this but none that I find fit what I'm looking for.
Please help!
