0 & 1 facts: Instant! Zero makes everything zero, one keeps it the same
2 facts: Just double the number (2×7 = 7+7 = 14)
5 facts: Always end in 0 or 5 (5×6 = 30, 5×7 = 35)
10 facts: Add a zero to the end (10×8 = 80)
9 facts: The digits add up to 9 (9×4 = 36, 3+6 = 9)
Practice daily: Even 5 minutes helps build speed!
🎯 Challenge Yourself:
Start with easier levels (0, 1, 2, 5, 10) to build confidence and speed.
Once you can do 20+ questions per minute on these, move to harder facts like 6, 7, 8, 9.
The mixed levels will really test your mastery!
