I used to do this. It's because of the confusing presence of the AC button. The UI has made clear to you that there are multiple levels of cancellation, one can in fact "really cancel." We know full well that there is some overcomplex internal state to the device, and rather than reading the manual for a calculator (honestly) we hammer the cancel button a few times, just to make sure.
- andyjohnson0 13y agoI hadn't thought of that, but it makes sense. A quick search reveals that some calculators have an AC button (clear everything) and a C button (clear last entry), while others have C (clear everything) and CE (clear last entry). Definitely confusing.
- JonnieCache 13y agoI'd forgotten about CE. Even worse.
