Hi.
I am doing an uncertainty analysis and I need to be able to work with numbers and their associated uncertainties.

If we say I have the following:
a = 10+-0.5
b = 20+-0.7

And I need to find:
c = a + b
d = a * b
e = a / b

Is there a function in Excel that can easily add, multiply and/or divide values including the uncertainties?

The math behind it is somewhat simple, but will take up a lot of work (and carry the risk of making a mistakes) if I have to write the full formulas for these operations.
