The task below is a classic math riddle from primary school. It is important to remember the order of operations if you want to get the right result, which is not easy after all these years.
Below we can see the challenge. Can you solve it?
Can you handle it? If not, you can find the answer after the picture below.
Here is the solution
The correct answer is 288. How did we end up with that number? We’ll walk you through the process.
First, we have to calculate the number inside the parentheses, 9 + 3 = 12. After that, our problem looks like this: 48 ÷ 2 (12).
Then we remove the parentheses and add a multiplication sign: 48 ÷ 2 x 12.
Then we solve the problem from left to right, which results in 288.
