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.

9 = I | 7 = U | 8 = J | 12 = O | 11 = W | 20 = R | 19 = M | 16 = N | 10 = A | 18 = D

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.
