This puzzle is a centerpiece of a Logical Reasoning IQ Intelligence Test. It evaluates your mathematical logic and attention to detail—two essential components of Brain Fitness and Cognitive Health. Solving such puzzles is an excellent way to support Healthy Aging. Let's solve the mystery step-by-step: First Row: Three triangles sum up to 9, which means one triangle represents 3. Second Row: Three circles sum up to 12, which means one circle represents 4. Third Row: One triangle (3) plus two squares equals 15. Subtract 3 from 15 to get 12, then divide by 2. Thus, one square represents 6. The Final Equation Challenge: The final line is: 3 + 4 x 6. It is crucial to follow the order of operations—Multiplication comes before Addition: First, calculate 4 x 6 = 24, then add 3. The final correct answer is 27. Stay Sharp Tip: Solving visual math equations is a fantastic exercise for your brain's Problem-Solving skills.
