Topics: anagram, codeword, letter map, rational numbers, rounding

Each correct answer gives a number. Use the scrambled letter map to translate those numbers into letters. The five letters you uncover form an anagram – solve it to unlock the codeword. Round normally to get to a rational number, if needed.

1 = I | 15 = P | 19 = T | 13 = N | 0 = O | 11 = S | 17 = G | 2 = Z | 3 = L | 14 = B

Code Breaker – Hard

Handle multi-solution algebra carefully. If you factorise or solve a quadratic, the puzzle may instruct you to choose a specific root.

  • When you get two solutions, pause and apply the instruction: positive, negative, larger, or smaller.
  • Only then translate the chosen number into a letter.
  • Keep the rejected solution written down (lightly) so you can sanity-check your choice if the final word doesn’t form.
