Calc Tape Calculator Pro

About this app

Finally, a calculator that works the way you think! Ever wonder why your calculator gives you a different answer than you expected? Our app solves that with Dual Calculation Logic:

Mode 1: The Math Professor (Smart Mode) – For complex equations, this mode uses the correct mathematical rules, prioritizing multiplication and division (PEMDAS/BODMAS). You get the accurate, scientific result every time. Example: 2+2x2 = 6

Mode 2: The Adding Machine (Normal Mode) – For everyday use, this mode calculates strictly from left to right. If you prefer 2 + 2 before you multiply, this is the mode for you. Example: 2+2x2 = 8

You choose your method. Never get the wrong answer again because of calculation confusion!

Simply the best editable tape calculator with history.
