Exponent Calculator vs MistakeBook

The iOS Exponent Calculator App was created in response to visitor requests from our popular online Exponent Calculator. Visitors to our site wanted a standalone Exponent Calculator that can be used in remote areas where there may not be a strong Internet signal. This app does not require an Internet connection, so you can use it anytime and anywhere. The goal was to make the app intuitive, clutter-free, fast to operate, and easy to use. This app can add, subtract, multiply, and divide numbers with exponents. In other words, the Exponent Calculator App is the only exponent app you will ever need! We hope that the Exponent Calculator App will become one of your favorite math apps.
