Apparently the iOS calculator has had a scientific mode since 2008

At the moment I realized that the iPhone’s built-in calculator app has a scientific mode — and all it’s important to do to entry it’s flip your cellphone on its facet. If you happen to’re the kind of one who retains your cellphone completely in portrait lock (like me), this may come as a shock to you, because it did to many people right here at The Verge.

This unlocks all kinds of performance, like including numbers to reminiscence, parentheses, exponents, and all these trig capabilities from again in highschool.

Or for extra critical math, there’s the TI-30XS, which may make some issues (like fractions) really easy it nearly seems like dishonest.
