🧠 Arithmetic Puzzles

📌 What Are Arithmetic Puzzles?

Arithmetic puzzles are brain teasers or problems that involve numbers and basic arithmetic operations such as addition, subtraction, multiplication, division, or a combination of these.

They test your:

• • Numerical reasoning
• • Logical thinking
• • Problem-solving skills

Unlike straightforward calculations, arithmetic puzzles require you to identify patterns, relationships, or hidden rules to find the solution.

📚 Common Types of Arithmetic Puzzles

1. • Number and Operation Puzzles: Find the missing number or operation.
   Example: 3 + ? = 10
2. • Magic Squares: Arrange numbers in a grid so sums of rows, columns, and diagonals are equal.
3. • Cross-number Puzzles: Like crossword puzzles but with arithmetic clues.
4. • Digit-Based Puzzles: Involve manipulation like reversing or summing digits.
5. • Arithmetic Expressions: Find values that make an expression true or balance equations.

🛠️ Strategies for Solving Arithmetic Puzzles

• • Step 1: Understand the Problem – Identify what’s given and what’s asked.
• • Step 2: Look for Patterns – Check for symmetry or arithmetic sequences.
• • Step 3: Break Down the Problem – Divide complex problems into smaller parts.
• • Step 4: Use Logical Reasoning – Apply arithmetic rules and logic.
• • Step 5: Verify Solutions – Ensure all conditions are met.

🧩 Examples of Arithmetic Puzzles

Example 1: Find the Missing Number

2, 6, 12, 20, ?

Solution: Differences: 4, 6, 8 → next difference is 10 → 20 + 10 = 30

Example 2: Magic Square (3x3)

Use numbers 1 to 9 so that each row, column, and diagonal sums to 15.

Example 3: Digit Puzzle

The sum of the digits of a two-digit number is 9. The difference between the digits is 3.

Solution: Let digits be x and y

• x + y = 9
• |x - y| = 3

Possible solutions: (6,3) or (3,6) → Numbers: 63 or 36
