Learn it Multiplying by 10, 100 or 1,000 moves every digit 1, 2 or 3 places to the left (zeros fill the empty places). Dividing moves them right.

Example: $47 \times 100$ and $3{,}600 \div 10$

  1. $47 \times 100$: digits move 2 places left → 4,700.
  2. $3{,}600 \div 10$: digits move 1 place right → 360.
