  9. [R10] Calculator for iPad! 1/5 · US Google Ads Turn Calculator Into Crapulator: It was fine until the google ads started getting slapped up over the keypad. But even if you delete the ad you’re left with a large box obscuring the keypad. It proudly says the ad was removed by google. Idiots!

I would love to give it 5 stars but when it is in split screen mode, I can’t see any way to square a number, or use any other exponents. This is essential to me as I need to do calculations while simultaneously writing the result on my iPad. I would love if this feature could be add
