@[email protected] i get it, but the ui does not reflect that. theres almost no way for the user to know that the app remembered enough context to perform such a computation. in other words, if i re-opened the app after i typed 50+50* - i wouldnt really be able to tell the difference. i just checked, unlike +-, */ operators in ios calculator in fact don't act exactly the same way, their buttons stays active as if i was holding it until i start typing a number. which is better than nothing, but still an awful ux tbh
