Euclid Lab vs Math From Counting to Calculus

Explore the 48 propositions of Book I of Euclid’s Elements through reading, construction and proof practice. Euclid Lab separates proposition reading, straightedge-and-compass work and reasoning so you can focus on one activity at a time. Arrange supplied proof blocks to connect premises to conclusions. Scored exercises use semantic checks of geometric relationships and logical dependencies, not the appearance of a drawing or AI grading. Progressive hints and complete solutions, shown on request, help when you get stuck. I.7 currently offers unscored reading, exploration and notes. Freehand notes are also unscored and are not automatically verified as correct proofs. Foundations and I.1–I.12 are free. I.13–I.24 and I.25–I.48 are separate, one-time in-app purchases. Buying one pack does not unlock the other. No subscription is required. Learning progress and notes are stored locally on your device. Learner profiles are not Apple Accounts, and no Euclid Lab account registration is required. Restore Purchases restores eligible content access; it does not synchronize learning progress.

FROM COUNTING TO CALCULUS Build your mathematics skills one step at a time. Follow a 46-stage learning journey, or choose any stage in Quick Play to practise a topic that matters to you. START WITH THE FOUNDATIONS Count objects and number sequences, then practise addition, subtraction, multiplication and division. Move on to powers, roots, fractions, decimals and percentages. BUILD CONFIDENCE WITH ALGEBRA AND GEOMETRY Solve equations, calculate areas and perimeters, and work with angles. Explore arithmetic and geometric sequences, exact trigonometric values and logarithms. EXPLORE ADVANCED MATHEMATICS Practise number theory, combinatorics, probability, complex numbers and 2-by-2 determinants. Continue to limits, power-rule derivatives and definite integrals, then try competition-style problems. PRACTISE AND PROGRESS - Career mode unlocks the next stage when you pass a round. - Quick Play lets you revisit any of the 46 stages. - Answer explanations help you understand each question. - Visual examples and diagrams bring mathematical ideas to life. - An optional timer, scores and a local leaderboard add variety. - Your career progress and settings are saved on your device. - Core learning content works offline. For learners building foundations, students revising familiar topics, and curious adults returning to mathematics. This is guided practice through increasingly advanced topics, at your own pace. Learning content is available in English, French, Spanish, German, Russian and Italian. Free download with advertising for eligible adult users and an optional one-time Remove Ads purchase. No subscription. Under-18 users and users who leave their age unspecified receive no ads. Verified previous paid owners retain ad-free access.
