Not sure, don't know much about op amps but sounds perhaps unlikely using only a single IC if what you mean is one device that can both add and subtract, maybe one exists, it sounds more like what I think is called a full adder, which isn't an op amp, and I imagine they are logic level input/output anyway.
If you mean something that the input ranges from 2.54 - 4.5VDC and the output is 0 - 10VDC, then at a guess, yes (but I don't think you'd get a variable output voltage), from the little I know, you'd set the input reference, and that sounds like a comparator.
This page about amplifier building blocks might clarify better if you can do that some way:
