=sum(C:C)
for the whole column.

=sum(c4:c65536)
for C4 and everything after that.

=sum(c2:c12)-sum(c5,c10)
is one way.

=sum(c2:c4,c6:c9,c11)
is another.

How would you indicate in a formula for Excel to choose an entire
column? Say, for example I want to sum up all the values in column C
starting from C4?

Also, how would I indicate to Excel to sum up values excluding a few?
Say I want to sum up columns C2 to C12 but not C10 and C5.

Thank you!
