Visual Math 4D vs Multiply Fun

Visual Math 4D is a graphical calculator that allows you to visualize and solve your mathematical equations. It supports various types of equations, such as polar, spherical, parametric and implicit equations, which can be visualized and animated in 2D and 3D. You can also plot and animate vector fields in 2D and 3D. Features: - solve equations - plot cartesian functions with intersections - plot polar- and spherical functions - plot parametric equations in 2D and 3D - plot complex functions (draw real part & imaginary part) - plot vector fields in 2D and 3D - plot implicit equations in 2D and 3D - plot contour maps ins 2D and 3D - support for complex numbers - vectors & matrices - truth- and value tables - trigonometrical and hyperbolic functions - piecewise-defined functions - logarithmic functions - logical & binary operators - definite integral - n-th derivations - statistical functions (nPr, nCr, rand..) - physical and mathematical constants with their units - animate variables - share content with other apps - no network connection required - and a lot more The app is easy to use and helps students and engineers to visualize and solve their mathematical equations.

Multiply Fun 19x19! transforms learning multiplication tables up to 19×19 into an exciting, visual experience. Designed for all ages, the app uses geometry—arrays, area models, and rectangular grids—to show how numbers combine, so learners see products instead of just memorizing them. With a friendly interface and interactive steps, Multiply Fun! builds skills and confidence—perfect at home, in class, or on the go. Features - Geometry-powered learning: visualize products as areas, split rectangles to decompose factors, and connect patterns to mental math - Interactive practice with instant feedback - Fun, activity-based challenges to keep users engaged Discover the magic of multiplication with Multiply Fun!
