# How Countries Teach Math

Compare how 10 countries teach mathematics side-by-side: PISA rankings, school start age, teaching methods (CPA, mastery, hagwon, Vedic), order of operations mnemonics (PEMDAS vs BODMAS), and calculator policy.

## Quick answer

PISA 2022 math rankings: 🇸🇬 Singapore (575) > 🇨🇳 China (591 in 2018) > 🇯🇵 Japan (536) > 🇰🇷 South Korea (527) > 🇫🇮 Finland (484) > 🇬🇧 UK (489) > 🇩🇪 Germany (475) > 🇫🇷 France (474) > 🇺🇸 USA (465). Key differences: Singapore uses CPA + bar models; Japan uses hatsumon (problem-posing); Korea adds private hagwon; Finland bans tests until 18; China requires rote multiplication tables by age 9.

## The Full Comparison

*India has not participated in recent PISA rounds. China figures are for Beijing-Shanghai-Jiangsu-Zhejiang (BSJZ) — not nationally representative. OECD average: 472.

## The Key Dimensions Explained

Symbolic algebra (working with variables like x ) is introduced earliest in England (age 11, Year 7), France (collège, 11–12), Germany (Gymnasium, 11–12) and India (Class 6, age 11). East Asian systems — Singapore, Japan, South Korea and China — formally begin algebra around age 12–13 at the start of secondary/junior high. The USA is the latest, with Algebra I typically taken in grade 8–9 (age 13–14), though many students meet pre-algebra concepts earlier.
Policy splits sharply. Singapore and China keep calculators out of primary school entirely (allowed from roughly age 11+), prioritising mental arithmetic and fluency. Germany and France introduce them from secondary/collège. Finland and the UK permit calculators from primary school, and the UK even sets dedicated calculator and non-calculator GCSE papers. The USA often allows calculators from grades 3–4.
