Goldbach's Conjecture
Read full descriptionHide full description
Fun and Challenging! Goldbach's Conjecture introduces students to an idea that has baffled mathematicians for centuries. In 1742, a Russian mathematician named Christian Goldbach wrote a letter to Leonhard Euler in which he proposed a conjecture. The conjecture stated that all even numbers greater than two can be expressed as the sum of two primes. This app challenges the player to find two prime numbers to make a target even number. Completing the activity involves using mental math skills. Goldbach Conjecture is designed to be a quick math exercise that teachers can use to provide extra practice in problem solving and an enriching experience for their students. Special sound effects make the game fun to use and the interactive design facilitate problem solving strategies.
Linear Algebra Visualizer
This app helps you understand linear algebra by visualizing matrix transformations. It shows the step-by-step math behind transformations, allowing you to build visual intuition and see how matrices work.
- Visualize matrix transformations
- Understand step-by-step math
- Build visual intuition
- See effect of TRS order
- Explore eigenvectors and eigenvalues
- Manipulate transformations

Ever wondered what a matrix is really doing? Whether you're learning it yourself or teaching students who are stuck, this app lets you visualise and manipulate matrix transformations, so you can finally see how and why they work. WHY IT CLICKS Most apps show you the answer. This one shows you why. The columns of a matrix are just where the basis vectors î and ĵ land. Column one is red. Column two is green. Follow those colors from your input, through the transformed vectors, into the step-by-step math. One number, traced all the way to its effect. With Linear Algebra Visualizer you: - Can finally build the visual intuition of linear algebra - Understand the math behind each transformation - Visually see why TRS order matters - Understand the effect of adding multiple matrices and translations - Watch eigenvectors and eigenvalues come alive BUILT FOR - Students surviving their first linear algebra course - Graphics programmers who want intuition, not just formulas - Teachers who need a live demo that lands - Anyone who's stared at a matrix and thought "but why does this work?" - Visual thinkers who've struggled to picture it all in their head Stop memorizing matrices. Start seeing them. Download Linear Algebra Vizualiser: Rotate, Scale, Shear, Reflect, Translate and learn to understand transformations visually. Ever wondered what a matrix is really doing?

Verdict
The clearest difference is price: Linear Algebra Visualizer at Free against Goldbach's Conjecture's $0.99. Linear Algebra Visualizer also leads on update cadence (every 2 weeks vs every 8 months). Goldbach's Conjecture's advantage is in-app purchases (none vs 3) and iOS requirement (12.0 vs 18.6). On ads and device support there is nothing between them.
