Before today, when you typed an equation into Google — say, “15 x 7″ — the answer (105, if you must know) would appear in bold above you actual search results. Now Google has gone one step further, giving you your answer on a virtual calculator.
The blue-hued calculator appears above your results, as before, and has 34 buttons, including standard trigonometric functions, exponents and buttons for the transcendental numbers, pi and e.
Bonus: It also works on mobile. In our quick test, it appeared in both Safari and Chrome on iOS and of course on Android as well. Although the scientific functions aren’t visible in portrait mode, they appear when you flip your phone to landscape — a trick Google’s borrowing from the iOS-standard calculator.
