Or if I intended to take the resulting percentage of some other number, then I would just shift the decimal in my head like you did and add .11 and .04. (As such, I don’t use percent keys much – if humanity had decided that perthirtyseven was interesting, then I’d use that key!)

However, I do think that bankers/businessmen/investment advisors like to speak in terms of adding 4% in the way that the calculator does it.

Thanks, this is for a financial exam I'm preparing for. I know I can easily convert to a decimal before inputting, but for simplicity, it would be nice to use the % sign, as that is consistent with my studies. I am still baffled the calculator does this, I cannot see the use case why converting to 11% of 4 makes any sense at all?
