Okay. But you can still use simply IF(C10="",0,...), and I still think that
is preferrable to IF(ISBLANK(C10),0,...).

Depends on your definition of "empty". I suspect you mean: __appears__
empty. The simplest formula is:

=if(C10="", 0, C5 - C10)

Do not use IF(ISBLANK(C10),"",...). ISBLANK returns true only when the
cell
is truly empty; that is, no formula and no constant.

If you use the formula above in H4, H4 might be an example of a cell that
__appears__ empty, but ISBLANK(H4) is FALSE.
