I made this app for my second son.
When I was a first grader, I made an app called “Ichinensei no Sansuu”, which is a sequel to that.

There are a total of 4 types of questions. All are two-digit calculations.

・ Addition (no carry)
・ Addition (with advance)
・ Subtraction (no carry-down)
・ Subtraction (with carry-down)

10 questions each. 100 points will be a perfect score with 10 points per question.

If you select the item “Seiseki”, you can see the highest grade, and if you select the item “Kiroku”, you can see the latest grade.
Since “Kiroku” also has a date and time, it helps to prevent sabotage.
