In Japan, most school education of calculation in math lesson is based on the column method because it is necessary to teach many students equally. However, in order to lay the groundwork for children's future development, it is necessary to create an environment conducive to mental math.

Even in Hong Kong's local and international schools, the column method remains the norm, but some schools are promoting and teaching mental math.
