This visual brain teaser looks like a simple addition problem, but the final equation contains details that can easily trick you! First, three pairs of shoes equal 30, meaning one pair is worth 10 and one single shoe is worth 5. Next, two caps plus a pair of shoes (10) equal 20. That means each cap is worth 5 points.

The third line shows two pairs of ties plus one cap (5) equaling 13. Subtracting 5 leaves 8, so each pair of ties is worth 4. Since each pair contains two ties, one single tie is worth 2 points. Now all three items have been identified, but the final equation is where careful observation really matters!

In the last line, the picture shows one single shoe, one cap and one single tie, not pairs. Their values are 5, 5 and 2 respectively. There is also a change in the mathematical symbol: multiplication replaces addition between the cap and tie. Remember the order of operations: multiplication must be completed before addition.

So the final calculation is 5 + (5 × 2) = 5 + 10 = 15. The correct answer is 15! 🎯 The common mistakes are counting a pair instead of a single item or calculating from left to right without following the multiplication rule.
