基本的算術與扭曲。解決使用邏輯運算數句。

This math puzzle comes from Teachbasix: creators of many logical math puzzles. All of them are great classroom resources for teaching primary grade children. They help develop thinking skills and problem solving abilities. This math game features various difficulty levels appropriate for primary grade or elementary school kids.

The rules are simple for a child to understand. You have to put +, - , x, or ÷ signs in the blank boxes so that the number sentences work. You need a bit of logic and a bit of calculation to solve each puzzle.

There are unlimited number of puzzles. You can monitor your child’s accuracy and average time taken to solve sums in each difficulty level. The badge system (silver, gold, platinum) provides a quick preview of your child’s progress.

This app is nominally priced. We believe an ad-free experience is imperative for your child to focus without any distraction.
