■ Systematic calculation training
Even if you know how to do calculations, it is not easy to do them quickly and accurately.
To achieve improvement in calculation skills in a short period, this software systematically includes carefully considered calculation problems, including the order of questions.
This software allows training in calculation problems for elementary school students from 1st to 6th grade, which they should acquire before entering junior high school. By continuously performing the daily training called "Today's Problem," which automatically selects based on your calculation ability, you can develop calculation skills.
And once you can solve all problems within the time limit, you will acquire the calculation ability to solve 63 fractions in 15 minutes.

■ Swap between upper and lower screens to write formulas
Normally, the problem is on the upper screen and the answer field on the lower screen, but by swapping the upper and lower screens, you can write formulas during calculations, eliminating the need for preparation of calculation paper when performing long division or common denominators.
After completing the calculation, swap the screens again to input the answer.
Additionally, you can set restrictions so that multiplication, addition, and subtraction are input from the right, and division from the left. This helps to learn the correct order of operations and reduces calculation errors.

■ Quick assessment of calculation ability
Includes simple calculation ability checks that can be completed in about 8 minutes on average. You can get an idea of your calculation ability (equivalent to a certain elementary school grade).
The learning content is classified by school year and by level or stage within each content, with certification exams for each level. If you want to study above the set grade, you must pass this certification exam.

"This software was planned to effectively develop the necessary calculation skills during the transition from elementary to junior high school (from arithmetic to mathematics). The calculations from 1st to 6th grade are systematically compiled, and simply solving them in order develops calculation skills that can withstand mathematics education, called the 'ラクダメソッド' (Camel Method). It combines the Nintendo DS, which is easy to use with two screens and a touch screen, with this systematic training, aiming to become a new basic form of training. It is intended not only for elementary and junior high school students but also for adults, including businesspeople who are weak in mathematics, who know calculation methods but cannot quickly produce answers."
