Hi

Im trying to make a small maple document, where i can calculate the moecule mass of any molecule. I want to assign all atoms with a value for its atom mass, but it will not let me unassign I, as this is the standard unit for imaginary numbers. Is there any way i can unassign I and give it a new value just in the current instance of the program? I dont want it to unassign I in other documents.

Thank you in advance

I have this simple sum equation: plot(y=sum(0.5^(n), n=1..x) It does not work for me at the moment, and my brain is getting fried from thinking at it. I think it might be because im using the x inside the sum parantheses, but it might also just be me having overlooked something or made a stupid little mistake, but could you please just help me?

Thank you in advance
