This deceptively simple puzzle has been driving people crazy online — and most get it wrong on the first try.

At first glance, the equation looks easy… until the order of operations steps in.

The Challenge

What is the correct answer to this?$$7 + 7 \div 7 + 7$$7+7÷7+7

Choose carefully:

• A) 49
• B) 39
• C) 15

The Correct Answer: 15

Here’s why:

According to the order of operations, division must be done before addition.

So we solve:

$7+7\div7+7$7+7÷7+7

Step 1: Division first

$$7 \div 7 = 1$$7÷7=1

Step 2: Add the remaining numbers

$$7 + 1 + 7 = 15$$7+1+7=15

✅ Final Answer: 15

Why so many people get it wrong

• 49 happens when someone incorrectly treats it like:

$$(7+7)\times7$$(7+7)×7

• 39 comes from mixing the operations in the wrong order.

The real trick is simple:
Always do multiplication and division before addition and subtraction — unless parentheses change the rules.
