This little math problem looks simple enough to solve in seconds, yet it’s easy to get a different answer when you read the equation from left to right without using the order of operations.
The equation is 6 + 4 × 3 − 5. Before checking below, decide which operation must be completed first.
The correct answer is 13. Multiply first: 4 × 3 = 12. Then 6 + 12 − 5 = 13. Doing the addition first changes the result, which is why the order of operations matters.
