The Crunch is The Chronicler’s daily number puzzle. Use all four numbers exactly once — with addition, subtraction, multiplication, division, and brackets — to reach the target. Every puzzle is computationally verified by Python across all permutations and bracket structures before publication.
This archive records every Crunch published since Vol. I, No. 15 (March 22, 2026), when the puzzle was introduced. Newest editions appear first.

( 5 × 8 ) − ( 6 ÷ 3 ) = 40 − 2 = 38 ✓
Python-verified — 2 distinct solutions (commutative variants). All four numbers used exactly once.
⚠ No valid solution exists for this combination. Python verification confirms 0 solutions across all permutations and bracket structures. This was The Chronicler’s inaugural Crunch puzzle; the Python verification standard was introduced in subsequent editions to prevent recurrence.

How Crunch Works
Each Crunch puzzle presents four numbers and a target. Using each number exactly once, combine them with any of the four standard arithmetic operations (+, −, ×, ÷) and any bracket arrangement to reach the target.
From Vol. I, No. 16 onward, every Crunch is verified computationally before publication: a Python script tests all permutations of the four numbers across all operator combinations and five distinct bracket structures, confirming at least one valid solution exists and recording the total solution count. The cleanest solution is selected for publication.
The solution count reflects mathematical distinctness — different orderings of numbers or operators that each independently reach the target. Higher counts generally indicate more approachable puzzles; counts of 2–4 are the most challenging.
