Decoding the Viral Math Puzzle: What Is 8 – 8 * 8 + 8?

If you have spent any time scrolling through social media, you have likely stumbled across a seemingly innocent math equation designed to spark thousands of heated comments, debates, and friendly arguments. One classic example that frequently makes the rounds is:

$$8 – 8 times 8 + 8$$

At first glance, it looks like a simple elementary school problem. Yet, ask ten different people, and you might get two or three different answers.

So, what is the actual answer? Let us break it down step by step and discover why this little equation trips so many people up.

The Short Answer

The correct answer is -48.

If you arrived at zero, sixteen, or fifty-six, do not worry—you are in good company with millions of internet users. But to see why -48 is the mathematical truth, we need to revisit the golden rule of arithmetic: the Order of Operations.

Step-by-Step Breakdown: Following PEMDAS / BODMAS

To solve any mathematical expression containing multiple operations (addition, subtraction, multiplication, and division), we follow a strict universal standard commonly remembered by acronyms like PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) or BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).

Here is how the rules apply to our equation:

1. Step 1: Multiplication First
   Looking at $8 – 8 times 8 + 8$, our eyes naturally scan from left to right. However, multiplication takes priority over addition and subtraction.
   First, we calculate $8 times 8$, which gives us 64.

   Our equation now transforms into:
   $$8 – 64 + 8$$

2. Step 2: Left-to-Right Addition and Subtraction
   Now we are left with only subtraction and addition. A common mistake here is assuming addition comes before subtraction because of how the acronyms are written. In reality, addition and subtraction have equal weight and are performed strictly from left to right.

   • First, compute $8 – 64$, which equals -56.
   • Next, add the final $8$: $-56 + 8 = mathbf{-48}$.

Why Do People Get It Wrong?

The reason this equation goes viral is because it preys on natural human cognitive habits:

• The Left-to-Right Trap: Many people read the equation like a sentence, calculating $8 – 8 = 0$, then multiplying by $8$, and adding $8$, which mistakenly leads them to an answer of $8$.
• The Grouping Illusion: Some viewers subconsciously assume symmetrical grouping, treating it as $(8 – 8) times (8 + 8)$, which zeros out the entire equation.

Mathematics is a precise language. Without universal rules like the order of operations, two engineers could calculate the safety load of a bridge differently, or a computer program could process financial transactions with chaotic results.
