Balance Math Go
Read full descriptionHide full description
Balance Math delivers algebra equation practice through an animated balance beam mechanic. Core mechanic: Solve for X in each equation. Enter your answer; the beam tilts proportionally based on your input vs. the correct answer. A balanced beam (zero tilt) confirms the correct value. Level set (30 equations, progressive difficulty): - Level 1-10: Single-step linear (X + c = n, aX = n) - Level 11-20: Two-step linear (aX + b = n, X - c = n) - Level 21-30: Mixed two-step (aX + b = n, aX - b = n, larger coefficients) Technical specifications: - Beam tilt: -0.1 to +0.1 radians based on answer delta - Progress: UserDefaults (Set of solved level indices), auto-persisted - Skip: Available on all levels, no penalty - Completion: Win overlay at level 30 Zero network calls. No account. No permissions required. No ads. No IAP.
