Adding and Subtracting a % from a sum

[danj4fsu]

I am trying to add or subtract a % (based on typing 5% or -5% etc) to a subtotal to get a new total. For instance, if in A10 I have a summed subtotal, I want to be able to type a positive % or negative % in A11. In A12 I want to total A10 plus or minus the % typed into A11. I hope that makes sense. TIA

Do you mean like this?

=A10+(A10*A11)

Well ****, I thought I did that but it wasn't working. Redid formula and seems to be right. Sorry for wasting time.
