if(a1+b1<0,0,a1+b1)

If your range is A1:A10, you could use
=MAX(0,SUM(A1:A10))

good luck

Thank you very much - one problem though: I really needed to have the difference of two numbers and if this difference is less than 0 it needs to be 0. For example: 25 - 35 = 0.

Thank you again!

=IF(A1-B1>=0,A1-B1,0)

Excel contains over 450 functions, with more added every year. That’s a huge number, so where should you start? Right here with this bundle.
