>The users who don’t need these features don’t have to know about them, don’t have to click through tutorials, or be pestered by hints. Welcome to the new iCalculator! To simplify your experience, the only operator button is "+", which now takes half of the screen, and is therefore easy to find and press, adding to the pleasure of using the calculator. You might ask, where's the "-" button? Was it stupid to remove it? No, it's brave! Don't be so negative about it; our UX studies show that "+" is statistically the most used button, and so your needs don't matter. If you need to subtract, swipe "+" button down; to multiply, swipe "+" right, and to divide, swipe "+" down. Swipe "+" up to raise to an exponent. To quickly square numbers, hold "+", then perform a square gesture clockwise aronud the button. To take a square root, perform it in reverse. You may notice that we have removed the digit buttons as well. That's because you don't need to type the numbers in - just say them out loud! Swipe the screen diagonally from the bottom left corner to the top right one to activate voice input. Note: digit buttons can still be enabled from the accessibility options in the system dialog. Note 2: voice recognition of operators is coming in a future upgrade. To clear your input, you can simply restart the app, no buttons needed. Note 3: you can enable a haptic shortcut in system acessibility settings: "Clear input by shaking phone". Finally, you can read this instruction manual by telepathically tuning into the lead engineer's mind, as it's not available anywhere else. Enjoy your intuitive iExperience!
