Japan is set to revamp its high school Mathematics curriculum by consolidating the existing subjects - Algebra, Geometry, and Calculus, known as ABC - into one comprehensive subject. This bold step from Japan's Ministry of Education is aimed to deepen comprehension and practical application of math skills. While the consolidation is ongoing, educators in the country have been given autonomy to implement these changes when they deem it feasible for students.

In Japan, the education system highly values structure and uniformity, with an aim to give every student equal opportunity. However, differing opinions exist on this reform, as some voice concerns over it potentially causing confusion while others believe it encourages a comprehensive understanding. The change dramatically shakes up conventions, symbolizing a significant shift in educational attitudes towards a more fluid, integrated approach to teaching maths.

In contrast, many high schools in the US and EU typically offer Algebra, Geometry, and Calculus as separate subjects, corresponding to different grade levels. This proposed reform in Japan represents a departure from this traditional approach, aiming to encourage a well-rounded understanding of mathematics, similar to some alternative education models in the Western world.
