The Great Internet Debate: Cracking the Code of 8 – 8 * 8 + 8

Every few weeks, a deceptively simple math equation pops up on social media, instantly dividing the internet into warring factions. People fiercely argue in the comments, absolutely convinced their answer is correct, while mocking everyone else’s mathematical literacy.

One such classic puzzle is the expression: 8 – 8 * 8 + 8.

At first glance, it looks harmless—just a few eights sprinkled with basic arithmetic symbols. Yet, a surprising number of people walk right into the trap. Let’s break down this viral math problem step-by-step, explore why it trips so many people up, and uncover the definitive answer.

The Secret Weapon: Order of Operations

Why do smart people get different answers to the exact same equation? The culprit isn’t a lack of intelligence; it is a forgotten schoolroom rule known as the Order of Operations.

If we read text like a book—strictly from left to right—we would calculate:

1. 8 minus 8 = 0
2. 0 times 8 = 0
3. 0 plus 8 = 8

While neat and tidy, this is entirely incorrect. Mathematics requires a universal grammar so that a scientist in Tokyo, a student in New York, and a baker in Paris all arrive at the same conclusion. That grammar is encapsulated in acronyms like PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) or BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).

Step-by-Step Breakdown

To solve 8 – 8 * 8 + 8 correctly, we must follow the rules of priority:

Step 1: Multiplication First

Multiplication and division take precedence over addition and subtraction. Before we can subtract or add anything, we must look for multiplication or division signs.

• Here, our core multiplication is 8 * 8.
• $8 times 8 = 64$

Now, substitute that result back into our original equation. It transforms from:
8 - 8 * 8 + 8
into:
8 - 64 + 8

Step 2: Addition and Subtraction (Left to Right)

With only subtraction and addition left, many people incorrectly assume addition must come before subtraction because “A” comes before “S” in PEMDAS.

However, addition and subtraction share the exact same rank. When operations share a rank, you evaluate them strictly from left to right.

1. First, calculate the subtraction on the left: 8 – 64.
   • $8 – 64 = -56$
2. Next, take that result and finish the final addition: -56 + 8.
   • $-56 + 8 = -48$

Why Do People Get It Wrong?

If you guessed 0 or 8, you aren’t alone! These are the two most common incorrect answers floating around comment sections:

• The Left-to-Right Mistake (Answer: 8): By ignoring the multiplication priority and marching straight across the line, people mistakenly treat the equation as (8 - 8) * (8 + 8), which evaluates to 0 * 16 = 0, or they misapply the operations entirely.
• The “Addition Before Subtraction” Myth (Answer: 72): Some incorrectly group the 8 + 8 at the end first, thinking addition trumps subtraction globally, throwing off the entire balance.

The Final Verdict

When you apply the universal laws of arithmetic correctly, the final answer to 8 – 8 * 8 + 8 is -48.

Math isn’t just about crunching numbers; it’s about following a shared language. The next time a tricky equation pops up on your feed, you’ll be ready to cut through the confusion, defend your logic, and claim victory in the comment section!
