Wikipedia:Articles for deletion/Multiplicative calculus
This appears to be a frequent reinvention. Review {{MR|2356052}} makes clear that this is just a disguised version of the standard calculus. Review {{MR|2724186}} points out that it is the same as the "Non-Newtonian calculus" of a 1972 book by that title, which MR didn't even bother to review. MR also didn't bother to review doi:10.1080/10511979908965937 in a mathematics education journal, reinventing the same wheel (nor did zbMATH review it). {{MR|2864779}} is a negative review of an attempt to show that this formalism is useful for differential equations; the reviewer disagrees. I might find it acceptable to have an article that points out that exp/log can be used to translate everything in the usual calculus into this form, and that reviews the history of reinvention of this not-very-deep concept, but that's not what we have here. Instead we have a lot of dancing around the point that this is all trivial, more or less as the first review I linked states. I think  applies: it might be possible to have something here, but not this
