What to Focus On

  • n^a means n multiplied by itself a times.
  • n is the base and a is the exponent or power.
  • 5^4 = 625.
  • Paper thickness doubles after every fold.
  • Doubling is exponential or multiplicative growth.
  • After 3 folds, thickness becomes 8 times.
  • A 2-digit lock has 100 combinations.
  • A 3-digit lock has 1000 combinations.
  • A 5-digit lock has 1,00,000 combinations.

Common Mistakes to Avoid

Power growth is the same as linear growth because both keep increasing.

The thickness after 10 folds is 10 times the original thickness.

4 + 4 + 4 and 4 × 4 × 4 mean the same thing.

Memory Tips
