How to Play Math Puzzle
This math puzzle challenges your logic and arithmetic with a unique twist. Match pairs from the strip to fill the 4×4 math puzzle grid, where each pair appears twice—once as a difference (larger minus smaller) and once as a product.
Understand the Puzzle
The math puzzle presents a 4×4 grid with target values. Below each target, input two values and an operator (- or ×) to match the target. Find which pairs from the bottom strip create each result in this puzzle.
Match Pairs with Operations
Each pair in this math puzzle must be used exactly twice, and all numbers must come from the bottom strip. For example, if your strip has 4 and 6, find cells with 2 (6-4) and 24 (4×6). Click the operator to cycle through ?, -, and ×. Remember: each unique number can only be used as many times as it appears in the strip (maximum twice).
Solve Hidden Values
Higher math puzzle difficulty levels hide some values. Use logic to deduce them: if you see target 18 and know one value is 3, the other must be 6 (6×3=18), or if you see target 5 and one value is 8, the other must be 3 (8-3=5).

Math Puzzle Rules
The Core Game Principle
This math puzzle follows one fundamental rule: every pair of numbers from the strip must appear in the grid exactly twice—once as a difference (subtraction) and once as a product (multiplication). The subtraction always uses the larger number minus the smaller number to ensure a positive result. This dual-appearance rule is what makes this math puzzle uniquely challenging and satisfying to solve.
Understanding the Puzzle Grid
The math puzzle grid presents a 4×4 grid containing 16 target numbers. Each cell in the grid represents either the difference or product of two numbers from your strip. Your task is to identify which pair of numbers creates each target value in this math puzzle and determine whether they were subtracted or multiplied together.
The Number Strip
Below the math puzzle grid, you'll find a strip of 16 numbers arranged in ascending order. Numbers may repeat in the strip based on how many times they're needed in the solution. These numbers form 8 pairs that you must match to the grid. In Easy mode, 5 numbers are hidden; Moderate hides 7; Difficult conceals 11. Hidden numbers must be deduced through logical reasoning based on the visible targets in the puzzle grid.
Number Pairing Rules
All numbers you input in this math puzzle MUST come from the bottom number strip. Each number can only be used as many times as it appears in the strip. For example, if your strip contains 6 and 8, you must find both 2 (8-6) and 48 (6×8) in the puzzle grid. You cannot use 6 with any other number, and 8 cannot pair with any number except 6. If a number appears multiple times in the strip, you can use it that many times. This constraint requires careful planning.
Operations in the Puzzle
The math puzzle uses two arithmetic operations: subtraction (-) and multiplication (×). For each cell, you select two numbers from the strip and choose the operation that produces the target. Click the operator button to cycle through the options. Both operations must be used for every pair—this is the key to solving this math puzzle. Remember: subtraction always subtracts the smaller number from the larger number.
Completing the Puzzle
You win the math puzzle when all 16 cells are correctly filled. Each pair from the strip must appear as both a difference and product, with no numbers left unused. The game provides immediate feedback: correct cells turn green, incorrect ones turn red. A perfect solution means every pair is properly matched and all operations are correct.
