I would write the SUMPRODUCT formula this way...

=SUMPRODUCT(--(A1:J1<A10:J10))=0

That way, you will not have to remember to adjust the 10 to reflect the
number of cells in a range (in case this formula gets used elsewhere on
ranges containing different numbers of cells).

Try one of these:

=SUMPRODUCT(--(A1:J1=A10:J10))=10

Or, array entered** :

=AND(A1:J1=A10:J10)

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the
SHIFT key then hit ENTER.

What formula could tell A1:J1 = A10:J10?
