Each color theme has its own, actual Grand Piano major scale! It's Chopin-awesome!

We spare you one unnecessary tap at a time. ## Classicalc calculates result using mathematical order of operators (× ÷ + -) so if you would like to add 1 to 1 and then multiply the result by 2, you should write (1 + 1) × 2 instead of 1 + 1 × 2 ## You can start your calculations on your iPhone, then Continue on your Apple Watch, and the other way around. ## Your most recent equation is always saved, even if you shut the app. When you run it again, The formula is instantly there. ## 14 great-looking backgrounds with related actual Grand Piano major scales. Change colors and major scales on iPhone app (by pressing little diamond in top-left corner) to change colors on Apple Watch. ## In case the numbers bore you, you can always play a song. It's Chopin-awesome! *** Tips *** - long press "backspace" button to clear whole expression (you can also force touch on your Watch) - long press the result on your iPhone/iPad to copy it to the system clipboard
