A slide rule adds.

And it can be used to drive nails if you are so inclined, but that doesn't make it a hammer.

Note that in the instruction manual of a slide rule, nowhere does it mention using the rule for addition and subtraction.

That one CAN use it for addition is a curious coincidence resulting from the fact that the log scales are linear. Thus, though one could add with it, a slide rule is NOT an "adding machine" in the normal meaning of the term.

Thank you. This is all that I stated and what I demonstrated.

(You cannot add using a "slip stick")

Yes, you can. Use the C, D, and L scales.(I have a Post)
