Önce çıkma tuşunun aktif edilmesi daha sonra tekrar ikinci kez alttan yukarı çıkma tuşuyla çıkmamız gerekiyor. Bu da çok can sıkıcı oluyor. Tek hareketle uygulamadan çıkılması için bir güncelleme yaparsanız çok iyi olur. Ayrıca ekranı basılı tutmadan tek bir tuşa basarak silebilmek için C tuşu eklenirse çok daha iyi olur ### 3/5 — Needs an Update *2021-10-06* The calculator should have an ALL CLEAR Should be able to change colour and to a Bright one Both features could be included to the paid version Thanks ### 5/5 — Tebrikler *2020-12-24, version 1.1.1* Güzel düşünülmüş ellerinize sağlık ### 1/5 — реклама в калькуляторе (?) серьезно? *2020-10-26* да иди та знаешь куда, волшебный... Короче, это кринж, добавлять с такое приложение рекламу, пошёл с очко, за это шакальему оценка для шакальего поступка ### 5/5 — Çok beğendim👍 *2019-10-31, version 1.0.6* Çok güzel.. bir önceki işlemin sonucu neydi, hay aksi unuttum derdi bitmiş👍 ## Frequently asked questions about Qnum › Calculator ### What is Qnum?
