Joan-ho Mathematics Research Institute developed the 'Joan-ho's National Arithmetic' app to provide computational learning experience for online and offline students.

A fun and systematic math training program for elementary and middle school mathematics that allows you to enjoy learning how to solve arithmetic problems like a game and increase your sense of accomplishment by leveling up as you learn.

■ Introduction to Joan Lake calculation: This is a brief introduction to Joan Lake calculation.

■ My Information: You can check information for each member.

■ Curriculum: You can check the score and frequency information of what you learned in this week's curriculum and this month's curriculum.

■ Jo An-ho Arithmetic Learning: Try solving various arithmetic problems in today's learning and overdue learning.
- You can study today’s study list of 15 to 20 sets of problems.
- Overdue learning A list of questions that have not been studied in the past week is displayed.
- Membership level icon displayed, question mark displayed for problem information (explanation of calculation concept)

■ Jo An-ho calculation statistics: You can view monthly learning statistics, weekly statistics, weekly rank, passing items, and monthly rank information.

■ Points: Points are awarded when you complete all of today's learning or completely pass each item with a high score.

Thank you for your hard work on your math workbook.
It will be faster in 2 months, and in 6 months you will be asked where you learned it. Now leave ‘Arithmetic’ to ‘Jo An-ho’s National Arithmetic’, which children can enjoy, and focus only on ‘Thinking logically’, which is the original goal of mathematics.

When looking at mathematics as a language, operations are ‘Ganadara…’ in Korean. ’ is the same. ‘Let’s go… ’ and can’t speak Korean well, and that doesn’t mean you can’t speak Korean well. Just because you’re good at ’ doesn’t mean you’re good at Korean. In mathematics, operations are just that, no more, no less. Computation is essential, but just being good at computation does not mean you are good at math. 80% of Korean students have become addicted to calculations and solving tangible problems, failing to think. For calculations, you only need to thoroughly perform ‘small number calculations’ used in middle and high school. Please leave calculations to ‘Jo An-ho’s National Calculus’ and raise children who can think with concepts.

Mathematics interpreter Joan Ho has raised the grades of countless children for 25 years and is the only conceptual expert in Korea who has published more than 30 mathematics books. Only the operations that will be used in advanced mathematics were carefully selected, and the inevitable side effects of the operations were minimized and programmed to be completed in an average of 3 years.

You can enjoy Jo An-ho's systematic calculations with conceptual explanations that you can't find anywhere else.
