If positive number say yes if negative say no

Question

I'm looking for a way that I can get the sum of 2 boxes when the formula goes through to present a yes or no in another box in the text of "Yes!" or "No!"

An example is if a1 = 4 and b1 = 5 I want c1 to run something like this:

c1 = sum(a1-b1<0 say no, a1-b1>0 say yes)

Answer 1

Try the following:

=IF((A1-B1)<=0,"No!","Yes")
