> I worry that the calculator we’ve known and loved is not long for this Earth. This month, when I upgraded my iPhone to the latest operating system, iOS 18, it came with a refreshed Calculator app. The update offered some improvements! I appreciated the vertical orientation of its scientific mode, because turning your phone sideways is so 2009; the continuing display of each operation (e.g., 217 ÷ 4 + 8) on the screen until I asked for the result; the unit-conversion mode, because I will never know what a centimeter is. But there also was a startling omission: The calculator’s “C” button—the one that clears input—was gone. The “C” itself had been cleared.
