Most calculators do not have a direct symbol for infinity (∞). However, there are still ways you can get infinity and negative infinity (or close to it) on Android. The easiest way is to use Google Calculator in your web browser. Still, you can also download a third-party app that supports entering positive and negative infinity, like Desmos Graphing Calculator, or use your Android's built-in calculator to get something close to infinity. This wikiHow article teaches you how to write negative infinity and infinity on an Android calculator.

QuestionWhy won't this trick work for me?Harrison TruongCommunity AnswerCertain calculators calculate negative infinity as NaN (Not a Number), so there aren't many calculators that calculate log(0). In fact, log(0) is undefined.
