İşaret Kuralları - Toplama ve Çıkarma

Pozitif ve negatif sayılarla işlem yaparken her durumda uygulanacak basit kurallar var. Bu kuralları ezberleyince hiç zorlanmayacaksın!

Toplama işlemlerinde aynı işaretli sayıları toplarken işaret değişmiyor. Yani (+) + (+) = (+) ve (-) + (-) = (-) oluyor. Farklı işaretli sayılarda ise büyük sayının işareti sonucu belirliyor.

Çıkarma işlemlerinde en önemli kural şu: küçük sayıdan büyük sayı çıkarılırsa sonuç her zaman negatif çıkar. Mesela 5 - 8 = -3 gibi.

💡 İpucu: İşaretli sayıların toplamında hangi sayı daha büyükse, sonuç o sayının işaretini alır!

Çarpma ve bölme kuralları ise çok net: aynı işaretli sayılar çarpılırsa/bölünürse sonuç pozitif, farklı işaretli sayılar çarpılırsa/bölünürse sonuç negatif olur. (-) × (-) = (+), (+) × (-) = (-) şeklinde hatırlayabilirsin.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
