*NOTA: hay un botón de traducción en la columna superior derecha de esta página.*

You can see the quasi-horizontal math learning stagnations across the world in most of the regions according to the PISA math 2003-2018. For most of the countries, the math poverty percent shares stay low with the little improvements.

- The western OECD countries
- The USA states
- Latin America & Caribbean (LAC) countries
- Caribbean island countries (mostly based on CXC exams for the Caribbeans)
- Arabic-speaking MENA oil-richest Persian gulf countries and the Islamic pacific countries
- Islamic countries in the Pacific ocean (Bahasa Indonesia, Brunei Darussalam, Malay speaking)
- others (South Korea, Israel)

**Some of the selected countries’ PISA math average scores going horizontal mostly for the past 15 years or so.**

**The original MMU1 operations (2017) to boost the math worst half to the math best half average quickly with its massive positive economic impacts.**

**Math progress or stagnations from the TIMSS math grades 4th or 8th scores: the 2 arrows are the MMU 0.5-0.7 operations of the slower versions (assuming the transformation impacts can be done in several years)**
