Visual math teasers are a great way to test your basic arithmetic skills, understanding of square roots, exponents, and the classic order of operations (PEMDAS/BODMAS).

In the puzzle image above, three kids sitting in front of plates of cookies claim different mathematical amounts:

  1. Boy on the Left (Blue Shirt): “I ate $\sqrt{64}$“

  2. Boy in the Middle (Striped Shirt): “I ate $7+2(2+2)$“

  3. Boy on the Right (Green Shirt): “I ate $22-3^2$“

By solving each expression step-by-step, we can determine who ate the most cookies.

Step-by-Step Breakdown

Let’s evaluate each child’s math expression:

1. Boy in the Blue Shirt (Left)

  • Expression: $\sqrt{64}$

  • The square root of $64$ is the number that, when multiplied by itself, equals $64$.

  • Since $8 \times 8 = 64$, $\sqrt{64} = 8$.

  • Total = 8 cookies

2. Boy in the Striped Shirt (Middle)

  • Expression: $7 + 2(2 + 2)$

  • Following the Order of Operations (PEMDAS/BODMAS):

    • First, solve inside the parentheses: $2 + 2 = 4$

    • Next, perform multiplication: $2 \times 4 = 8$

    • Finally, perform addition: $7 + 8 = 15$

  • Total = 15 cookies

3. Boy in the Green Shirt (Right)

  • Expression: $22 – 3^2$

  • Following the Order of Operations:

    • First, calculate the exponent: $3^2 = 3 \times 3 = 9$

    • Next, perform subtraction: $22 – 9 = 13$

  • Total = 13 cookies

The Final Comparison

  • Boy on Left = $8$

  • Boy in Middle = $15$

  • Boy on Right = $13$

The Final Answer

The boy in the middle (striped shirt) ate the most cookies with a total of 15!

Why Order of Operations Puzzles Go Viral

  • Common Pitfalls: People often evaluate math problems strictly from left to right, forgetting to prioritize parentheses and multiplication before addition.

  • Fun Memory Refresh: Serves as a quick, satisfying refresher on foundational middle school math concepts.

  • Engaging Online Debates: Simple arithmetic expressions with multiple operations frequently spark lively discussions in social media comment sections.
