What’s the Value of Circle + Triangle + Square? Find Out How!

Here’s a quick puzzle to put your logic skills to the test: three simple equations involving a circle, a triangle, and a square. First, circle times circle equals 16. Next, circle times triangle squared equals 36. Then circle times triangle times square equals 72. What happens when you finally add circle, triangle, and square together? At first glance, it seems like guesswork, but there’s a clear pattern to follow. Read on for a concise, step-by-step breakdown that reveals exactly why the answer is 13—and see if you can solve it faster than your friends!

Common Pitfalls

  • Skipping the First Clue: If you don’t see that “circle times circle equals 16” means the circle must be 4, you’ll get lost.
  • Guessing Instead of Solving: Random trials slow you down when a straightforward approach works best.
  • Mixing Up Operations: Confusing multiplication with addition or doing the final sum too early leads to errors.

Step-by-Step Solution

Find the Circle

  • From “circle × circle = 16,” we know the circle equals 4.

Find the Triangle

  • Substitute into “circle × triangle × triangle = 36”:
  • 4 × (triangle²) = 36 → triangle² = 9 → the triangle equals 3.

Find the Square

  • Use “circle × triangle × square = 72”:
  • 4 × 3 × square = 72 → 12 × square = 72 → the square equals 6.

Compute the Sum

  • Finally, add them: 4 + 3 + 6 = 13.
