Subtract Cell A1 from A2 and vice versa

[fjwag3]

New Excel user coming from open office.

Simple subtraction, eg, A1, A2, A2, A1. I need the solution in Cell B opposite the > number.
=IF(E7>E8;E7-E8;"") is the formula in Open Office. The double quotations do not get the job done in excel 2007.

=MAX(A1:A2)-MIN(A1:A2) this formula subtracts and places in the one cell, I need it either/or, adjacent to the > #.

9 3
6

6
9 3

Thanks in advance
