Welcome to MechMath! A good-looking, easy-to-use calculator. Since there is no official calculator for the iPad, and I haven't been able to find any other calculators with a good aesthetic, I decided to make my own. Perhaps the function of the MechMath is very simple, but the appearance must be qualified. Features of mechanical abacus: - UI is mechanical keyboard style - When the button is clicked, there will be a button sound effect that mimics the mechanical keyboard - Supports simple addition, subtraction, multiplication, and division of integers and decimals, but does not support complex scientific calculation requirements, such as square root, etc. - Accepts input of up to 11 characters, more input will not respond.
