What to Focus On

  • A letter can represent an unknown number.
  • The trick always ends with 2.
  • Algebra explains why the result is fixed.
  • The final number equals 100M + 165 + D.
  • M stands for month number and D stands for day number.
  • The day has at most 2 digits because it is at most 31.
  • Each number in a pyramid is the sum of the two numbers below it.
  • Start by writing equations for adjacent rows.
  • Solve the middle unknown first when possible.

Common Mistakes to Avoid

The 'Think of a Number' trick gives different answers for different starting numbers.

The date trick final number is the date itself, so the last digits can be read directly without subtracting 165.

In the date trick, the month and day can be split in any way, even when the final number has only three digits.
