📝 Translation Quality

Criterion	Score
Accuracy	10/10
Fluency	9/10
Terminology	9/10
Formatting	10/10
Overall	9.5/10

Summary: The changed sections (frontmatter, 'Applications in Economics', and 'Exercises') are translated accurately and fluently, with correct adherence to the glossary and language policy. Technical terms remain in English, exercise directives are preserved byte-for-byte, and the economics explanation is faithfully rendered. No syntax errors or major issues were found; only minor stylistic notes apply. The Exercises section and its exercise/solution directives are preserved exactly as required by policy, with no unnecessary translation. Technical terms (vector space, matrix, eigenvalue, Leontief inverse, etc.) are consistently kept in English per the glossary. The 'Applications in Economics' section accurately conveys the meaning of closure and additive inverses in economic modeling context. Math blocks, code cells, and code comments are left untouched, matching policy requirements. Frontmatter translation metadata is correctly added without disrupting YAML structure.

Suggestions:

• [minor · fluency] lecture.md — #### Applications in Economics: The sentence 'inverses-ന്റെ നിലനിൽപ്പ് debts, obligations എന്നിവ model ചെയ്യാൻ നമ്മെ അനുവദിക്കുന്നു' is accurate but slightly clipped compared to the source's 'the existence of inverses allows us to model debts and obligations' — minor stylistic smoothing could improve readability, though this is not an error.
• [nit · formatting] lecture.md — ## Exercises: The Exercises section correctly preserves all exercise/solution directives byte-for-byte in English per policy, and the heading itself is kept in English as required. No issues found here.

🟡 Changes recommended

The new exercise solution cell uses an inconsistent {code-cell} language tag (python3 vs python elsewhere), which may cause tooling/parsing inconsistencies.
