ひっさん　算数計算 與 Bunsuu calculator 使用情況與統計

[Overview] This is a calculator that allows you to check intermediate steps in fraction calculations. It was created with the aim of enabling supervisors such as educators to easily identify areas of calculation errors. [Main features] 1. When the "=" button is pressed, the calculator switches to fraction mode and displays the intermediate steps of fraction calculations. 2. In addition to basic arithmetic operations between fractions, it also supports mixed fractions, decimals, and negative numbers. 3. By clicking the "=" button or the calculation result display area, the fraction screen can be hidden and the calculator can be used as a normal calculator (allowing continuous calculations). Students should avoid using this calculator unless they cannot find errors in their calculations (it will decrease their computational skills).
