0 = 0 is one of the most general mathematical facts, 
compatible with any theory (even with the topos theory, 
as it was indicated that the latter is essentially 
a restricted form of Zermelo). 

In view of this, would R.Tragesser consider 0 = 0 as 
even more important that the topos theory for f.o.m. ?
