After upgrading the Calculator app, users will see the cursor blinking in the text box, a visual indication that the text box is now editable. The cursor can be dragged around or a double tap on part of the formula will have it selected. A long press also will achieve the same result. Highlighting a formula will bring up a context menu with the option to cut, copy, paste, select all and MS (Memory Store).
Google added another small visual change to an existing feature. The Calculator has a drawer to the right side of the app. Slide the drawer to reveal more math operators. In this update, Google added a little arrow as yet another visual indicator.
Finally, the app icon has changed with the equal sign less prominent. Get the update in Google Play Store.
