If Bitcoin currency conversion is too trivial a use for you, loyal Bing user, perhaps the addition of a calculator will help solve the equation of your unhappiness. Simply type a math problem into Microsoft's search engine and, as Windows Phone Central has noticed, an interactive scientific calculator will pop up with the answer. From there you can do as much math within a browser tab as your non-Googling heart desires. WPC also notes that while the calculator interface won't be making its way to Windows Phone, entering a math problem into the mobile flavor of Bing will still return the answer to your query. It's no graphing calculator, to be sure, but Mountain View wasn't built in a day, either.
