DragginMath vs Set Theory Foundations

DragginMath is a new way to teach, learn, and do algebra. This app converts equations into interactive pictures. Get serious about math: turn equations into playthings! Yes, it's fun, but this is definitely not a toy. See the internal structure of equations. Then commute, associate, distribute, factor, simplify, and solve by dragging math under your fingertips. This is real algebra, not something that sort of looks like it. Not a function-graphing app. Not restricted to a few limited examples or prepared problem sets. This app can do an astonishing amount of symbolic math, but it is aimed at the algebraic novice. Do you or your students need help understanding the order of operations? Unsure what the various algebraic properties are or how to use them? Is solving an equation just some arcane mystery? DragginMath lets you see and experiment with symbolic math concepts. You still have to direct the work yourself, but without burning through erasers or reams of paper, and without needing someone to check your work. DragginMath is not curriculum. It is a tool, and it is curriculum-independent. If your textbook has expressions and equations in it, DragginMath can help you teach it, or learn it. You might even enjoy doing it. Are you a teacher? Create animated lessons just by using the app as you normally would. Add annotations and homework problems, then email them to your class within the app. Students watch your lessons, do their homework, and email it back to you within the app. Returned homework is formatted for easy management.

Set Theory Foundations is an independent study app for learners who want focused practice in core set theory ideas, proof habits, and common reasoning patterns. It is built for beginners, students reviewing discrete math, interview prep learners, and anyone strengthening mathematical logic skills. Practice across four focused categories: - Fundamentals - Practical Skills - Common Pitfalls - Advanced Concepts Features include: - 160 practice questions - Every question includes an explanation - FSRS spaced-repetition intervals to review at the right time - Weak-point heatmap to show what needs work - Daily challenge for steady progress - Mock exams for timed review - Offline practice with no login required Use short sessions to drill definitions, operations, relations, functions, cardinality, proof techniques, and tricky edge cases. Review missed questions, track weak areas, and build confidence before class, exams, or self-study milestones. Practice offline, no login required.
