Tips for faster squares
Perfect for mental math drills and building speed with square numbers.
- Use (n+1)² = n² + 2n + 1 to jump between squares.
- Square numbers ending in 5 quickly: 35² -> 3x4=12, then 25 -> 1225.
- For numbers near 100: 97² = (100-3)² = 10000 - 600 + 9.
- For 2-digit numbers: (a+b)² = a² + 2ab + b².
- Common mistake: forgetting the middle term (2ab).
- Common mistake: arithmetic slip after a correct setup.
- Start with 2-20, then 2-50, then 2-100.
- Do 10-question speed sets to build pattern recall.

Squares Practice FAQ
Try 2-20 until it feels automatic, then increase to 2-50.
Memorize key squares (1-30), then practice using near-100 and (n±1) shortcuts.
Squares are a special case of multiplication, but training them separately helps you build instant recall.
