The Internet’s Favorite Trap: Decoding “8 – 8 × 8 + 8”

If you spend more than five minutes scrolling through social media, you are bound to stumble across a simple arithmetic equation dividing comment sections into absolute chaos. Grown adults will passionately argue, cite elementary school teachers, and claim the math system is broken—all over a handful of single-digit numbers.

One classic expression that never fails to spark a fierce debate is:

8 – 8 × 8 + 8

At first glance, it looks harmless. Yet, ask ten people what this equals, and you are likely to get a surprising variety of wrong answers before someone lands on the correct one. Let’s break down the math, uncover why this expression trips so many people up, and settle the score once and for all.

The Step-by-Step Breakdown

To solve this puzzle correctly, we rely on the universal rules of the order of operations, commonly remembered by acronyms like PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) or BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).

Let’s apply the rules step-by-step:

Step 1: Multiplication First

According to the order of operations, multiplication takes precedence over addition and subtraction. Before we can subtract or add anything, we must evaluate the multiplication part of the expression:

• $8 times 8 = 64$

Now, substitute that back into our original equation:

• $8 – 64 + 8$

Step 2: Left-to-Right Addition and Subtraction

This is where the trap is set. Many people mistakenly believe that Addition always comes before Subtraction because of how the acronyms are written. However, addition and subtraction share the exact same priority level. When they appear together, you must evaluate them strictly from left to right.

1. First, perform the subtraction on the left:
   • $8 – 64 = -56$
2. Next, add the remaining 8:
   • $-56 + 8 = -48$

The final, correct answer is -48.

Why Do So Many People Get It Wrong?

It is easy to mock viral math errors, but these equations tap into very common cognitive traps:

• The Left-to-Right Blindspot: A reader might read the problem purely sequentially without applying precedence, doing $8 – 8 = 0$, then $0 times 8 = 0$, and finally $0 + 8 = 8$.
• The “Addition Before Subtraction” Myth: Because PEMDAS/BODMAS places the “A” before the “S”, people often assume they must add the trailing $8 + 8$ first (making 16), and then subtract it from the multiplication result. Doing $64 + 16$ or mishandling the signs leads straight to incorrect answers like $0$ or $56$.
• The Human Need for Simplicity: Our brains love to find patterns and simplify things quickly. When numbers repeat themselves (like four 8s in a row), our intuition screams that the answer should be an intuitive number like $0$ or $64$, blinding us to the actual mechanics of the equation.

The Takeaway

Math isn’t designed to trick us, but shorthand human memory and social media algorithms certainly are! Equations like 8 – 8 × 8 + 8 serve as a fun reminder of why standardized rules exist in mathematics. Without a universal order of operations, engineers couldn’t build bridges, programmers couldn’t write code, and we’d all fail sixth-grade algebra.

Next time you see a math puzzle pop up in your feed, take a breath, trust your rules of precedence—and maybe keep a calculator handy before jumping into the comments!
