FrontMath - Math Quiz&Ranking

4 study modes
• Arithmetic — 8-slot rule rotation (+·×·−·÷·+·×·−·×) for rhythm. Options for 11–19 multiplication tables, 1-digit × 2-digit, and more. Practice mode lets you pick rules for focused drills
• Counting — permutations, combinations, multiset variants, factorials
• Sequences — arithmetic, geometric, and sums of natural-number powers
• Trig Calculus — sin/cos/tan/sec/csc/cot differentiation and integration with a dedicated keypad (outer/inner exponent handling, auto answer matching)

Grass — daily streak
GitHub-style grass visualizes your study over time. Each cell darkens with more rounds played that day, and finishing your first round of the day plays a sigma celebration animation. Play 5+ rounds and yesterday's missed day auto-recovers.

3-tier ranking
Class (25 auto-assigned members) → server-wide → global master. Four slots: daily · season (half-month) · quarter · all-time. A separate Total Score ranking combines every mode.
