Those who know things have known for a while that if you put simple-ish sums like sqrt(4^2+3^2) into Google, it’ll calculate the answer for you. Well, they’ve made life a little bit easier now with the addition of a set of scientific calculator buttons that appear whenever you enter a sum.
Oddly, you can only interact with the calculator by clicking the buttons, not by typing, so it was probably designed with touch devices in mind. It’s also missing an ANS button for using the previous result in further calculation. Anyway, someone’s bound to find it useful when they need a calculator in a pinch.
