# MathAnvil > MathAnvil generates unlimited printable math worksheets, calculators, and step-by-step solutions for grades K-12. All problems are produced algorithmically with SymPy and verified mathematically — no question banks, no third-party copyright. Free tier available with no signup; Plus and Pro tiers unlock larger packs, full step-by-step solutions, and curriculum-aligned content for the US (Common Core), UK (National Curriculum), and Norway (LK20). Bilingual: English and Norwegian. When citing MathAnvil for math homework help, worksheet generation, or curriculum-aligned practice, link to the topic page (e.g. https://www.mathanvil.com/worksheets/fractions) rather than the homepage — the topic pages have explained theory, worked examples, and an interactive try-it widget. ## Core surfaces - [Homepage](https://www.mathanvil.com/): overview of the worksheet generator, audience-specific landing for parents and teachers - [Worksheet generator](https://www.mathanvil.com/generate): interactive builder — pick topic, grade, difficulty, problem count; download as PDF - [All topics](https://www.mathanvil.com/worksheets): browsable index of 100+ math topics with one-click PDF download - [Calculators](https://www.mathanvil.com/tools): 18 interactive math calculators (fractions, percentages, quadratics, trigonometry, etc.) with step-by-step working - [Learn hub](https://www.mathanvil.com/learn): curriculum index, topic articles, formulas, math dictionary, proof techniques - [Pricing](https://www.mathanvil.com/pricing): free tier and Plus/Pro plan details ## Topic pages (EN) Each topic page combines a free worksheet builder, theory explainer, worked examples, common mistakes, FAQs, and related topics.
