Unraveling the Viral Math Trap: What Actually Happens in 8 - 8 * 8 + 8?

If you scroll through social media for more than five minutes, you are bound to stumble across a simple arithmetic expression tearing comment sections apart. People passionately argue, hurl insults, and swear by conflicting answers—all over basic elementary school math.

One of the most classic trick equations designed to trip up the internet is:

8 - 8 * 8 + 8

At first glance, it looks harmless. Composed entirely of eights and basic operators, it should take two seconds to solve. Yet, ask ten people, and you might just get three different answers. Let’s break down the math, decode the universal rules of calculation, and see why this little string of numbers causes so much chaos.

The Golden Rule: Order of Operations

The root cause of every viral math argument isn’t that math is subjective—it’s that people forget the Order of Operations. Universally taught as PEMDAS (in the US) or BODMAS (in the UK, Australia, and elsewhere), this rule dictates the strict hierarchy in which mathematical expressions must be evaluated:

1. P/B – Parentheses / Brackets
2. E/O – Exponents / Orders
3. M & D – Multiplication and Division (evaluated from left to right)
4. A & S – Addition and Subtraction (evaluated from left to right)

Notice where multiplication sits compared to addition and subtraction? It holds a higher rank. Therefore, we cannot simply read 8 - 8 * 8 + 8 from left to right like a book.

Step-by-Step Breakdown

Let’s tackle 8 - 8 * 8 + 8 using the proper rules:

Step 1: Handle the Multiplication

According to PEMDAS/BODMAS, multiplication takes precedence over addition and subtraction. We locate the multiplication part in the middle: 8 * 8.

• $8 times 8 = 64$

Now, substitute that back into our expression. The equation transforms into:

8 - 64 + 8

Step 2: Evaluate Addition and Subtraction (Left to Right)

This is where many well-meaning solvers stumble. Addition and subtraction share the exact same priority level. When they appear together, you must evaluate them strictly from left to right.

First, handle the subtraction on the left (8 - 64):

• $8 – 64 = -56$

Now, plug that into the final piece of the equation:

-56 + 8

Finally, add the remaining 8:

• $-56 + 8 = -48$

(Alternatively, you can group the positive terms: $(8 + 8) – 64 = 16 – 64 = -48$. Both paths lead to the exact same destination!)
