どこでもワーク　数学１年計算編 is an educational app developed by 株式会社　文理. It is a comprehensive workbook that fully corresponds to the school textbooks. The app is designed to help students practice calculations and prepare for regular tests. With over 100 questions, it offers a wide range of problem sets to enhance mathematical skills.

One of the key features of this app is the ability to record the intermediate steps of calculations. By using a virtual keypad, users can easily identify where they made mistakes. This feature promotes a better understanding of the calculation process.

The app also incorporates gamification elements to make learning more enjoyable. Upon completing a unit with all correct answers, users are rewarded with items that can be used to decorate the "Curio Room". The goal is to collect all the items by achieving a perfect score on every unit.

In addition, the app provides various user-friendly features such as the "Retry" function, which allows users to redo only the incorrect questions, and the ability to view related formulas. These features help users find a learning style that suits them best.

Please note that items can only be obtained by solving all questions correctly in a selected unit, either in sequential or random order. Various settings, such as sound effects, timer, keypad usage instructions, and learning history reset, can be accessed through the gear icon in the top right corner of the screen.
