A seemingly simple equation has sparked plenty of confusion: 20 + 20 ÷ 10 × 2 = ? At first glance, it may be tempting to calculate everything from left to right without considering the order of operations, or to assume multiplication should automatically come before division. But following the standard rules of arithmetic gives us a clear answer. 🧠

Using PEMDAS/BODMAS, multiplication and division have the same priority and must be handled from left to right. Start with the middle portion: 20 ÷ 10 × 2. First, 20 ÷ 10 = 2. Then take that result and multiply it by 2: 2 × 2 = 4. Addition is handled afterward because it has a lower priority.

Now place that result back into the original equation: 20 + 4. The final step is straightforward: 20 + 4 = 24. Therefore, the correct answer is 24, not 21 or 8. The important part of this puzzle is understanding that multiplication and division are treated equally when applying the order of operations.

So why do some people get 21? They may calculate 10 × 2 first, turning the expression into 20 ÷ 20 = 1, and then add 20 to get 21. But that changes the original expression by giving multiplication priority over division. When multiplication and division appear together without parentheses, work from left to right. Once you follow that rule, the puzzle becomes much easier—and the final answer is 24. 🎯
