Common Mistakes and Why They Happen

When solving puzzles like this one, many people make these common errors:

Miscalculating the Sum:

  • Rushing through the calculations can easily lead to mistakes when adding up the numbers, resulting in an incorrect total.

Overlooking Key Details:

  • The critical instruction here is that both rows must sum to the same total. Missing that can steer you off track.

Faulty Reasoning with the Missing Number:

  • Instead of setting up the problem with an equation, some solvers might try random guesses without systematically verifying the condition.

These pitfalls often result from either haste or failing to carefully assess every detail of the problem.

Step-by-Step Solution

Calculate the Top Row:

  • 7 + 5 + 3 + 4 + 6 + 8 = 33

Set Up the Equation for the Bottom Row:

  • 8 + 3 + 4 + 2 + 7 + x = 33

Add the Known Numbers in the Bottom Row:

  • 8 + 3 + 4 + 2 + 7 = 24

Solve for x:

  • 24 + x = 33 ==> x = 33 – 24 = 9

The missing number is 9.
