Math Riddle: Why the Answer Is NOT 80

At first glance, this equation looks easy: 8 × 8 + 8 × 4 = ? Yet plenty of people rush through it and end up with 80—or another incorrect number. The handwritten clue even warns, “Answer is: NOT 80.” So what makes this little puzzle so easy to get wrong? The trick is understanding the order in which mathematical operations must be performed.

Some people simply work from left to right, combining numbers before completing the required multiplication. Others add the middle numbers first or rearrange the expression in their heads. These approaches can produce wildly different answers, but standard mathematics doesn’t allow us to choose the order randomly. There is a specific rule designed to prevent exactly this kind of confusion. 🧠

The rule is commonly remembered as PEMDAS or BODMAS. After parentheses and exponents, multiplication and division are handled before addition and subtraction, working from left to right when operations share the same level. So in this equation, both multiplication sections must be completed before the plus sign is used. First, 8 × 8 = 64. Then, 8 × 4 = 32.

Now the equation has become 64 + 32. That final calculation is straightforward: 64 plus 32 equals 96. 🎯 So the correct answer is 96—not 80. The puzzle is a simple reminder that even basic-looking equations can produce the wrong result when we ignore the order of operations. Did you get 96 on your first try? 🔢✨
