Arlektra vs MathBench

Arlektra teaches electronics and circuits hands-on, with real-time Augmented Reality 3D instructions and animations through your phone or tablet. Now you easily learn, build and see the world of electronics and circuits like never before! When using Arlektra's complete learning kit, or the demo Arlektra Image Target, learners will: [SEE THEORY] Arlektra will allow you to easily visualize and comprehend the most difficult electrical concepts and theories, as they come alive right before your very eyes. You'll finally understand the unseen complexities of electrical theory, with vision and insight beyond your imagination. [BUILD CIRCUITS] Using step-by-step Visual (3D), Audio and Text instructions, Arlektra will teach you to build electrical circuits, with ease. You’ll learn to build various types of circuits, while using different electrical parts to do so - all without any assistance. [EXPLORE PARTS] Arlektra will allow you to see real electrical parts in detailed 3D exploded and 360 views - while you look through your mobile device. You'll learn about their inner workings and operation, and how they connect and work together in electrical circuits. [LEARN TOOLS] Arlektra will teach you how to you use a digital multimeter in ways that have never been done before, with 3D assistance. You'll learn a multimeters functions and how to test circuits and conduct basic electrical troubleshooting procedures. Arlektra comes with everything you want and need. No other app in the universe can teach you electronics and circuits like Arlektra. It will inspire and prepare you for the future, beyond your imagination! [Requirements]

MathBench turns math into hands-on reasoning. Do the same thing to both sides of a balance until only x remains. Drag parameters until a parabola passes through the target. Bisect an angle with only a compass and straightedge. Every move is checked for equivalence in real time. THREE SUBJECTS, 75 LEVELS Algebra Balance: linear equations, systems, quadratics and inequalities. Multiply by a negative and the sign must flip; divide by an expression in x and you may lose a root. Brainer levels are built around these traps. Graphs: linear, quadratic, inverse and absolute-value functions, shifts and stretches, and solving equations and inequalities by graph. Constructions: perpendicular bisectors, angle bisectors, perpendiculars, parallels, regular hexagons, circumcenter and incenter, tangents to a circle. Each subject has Intro, Core, Brainer and Mixed levels. 30 levels are playable right away; the other 45 unlock with Pro. A daily challenge and a review list bring back levels you solved with help. PRINCIPLE CARDS After each solve, a Principle Card explains why it works using the numbers from your own solve, such as x = (3 ± √17)/4 or 3² + 4² = 25. FIVE TOOLS • Exact fractions: simplify, common denominators, mixed numbers, repeating decimals, prime factorization • Equations: linear and quadratic with exact radicals, inequality intervals, 2×2 and 3×3 linear systems • Graphing: up to three curves with zeros, intersections and vertices • Triangle solver: find the remaining sides, angles and area, including the two-solution case • Statistics: mean, median, mode, range, quartiles, variance and standard deviation, computed exactly as fractions from integers, decimals or fractions Tool results are unlimited; hints are never consumed and undo is unlimited. PRO — ONE-TIME PURCHASE All 75 levels, full Principle Card derivations, step-by-step tool working, and a Free Bench you can edit and save (balance, graph and construction benches). Pro includes every worked answer and all Pro features. The first three fixed sample answers in each subject are free to view; all remaining answers unlock with Pro. One-time purchase. No subscription. PRIVACY All calculations run on your device and work offline. No account and no analytics SDK. Progress syncs through your own private iCloud. NOTE: MathBench is for understanding principles and practicing reasoning. Problems are original, not tied to any textbook, and no exam-score gains are promised.
