The knowledge we acquire in school is truly valuable. Of course, not everything is necessary in life but most of them will definitely be useful to you at least once. We want to share with you an exercise from a school textbook that has confused people online. It’s easy but at the same time difficult, see how difficult it will be for you.
The equation itself looks like this: 8 2 (2+2) = ?. The most common answer people get is 16 or 1, but is that really the case? If you got the same answer, keep reading to find out the solution.
The explanation is as follows: action in parentheses, then multiplication, then division. So one unit is obtained and it seems reasonable. How do you get a different answer? In fact, everything is not so difficult. You just need to do the division first, then the multiplication!
It’s worth noting that both answers can be correct. When determining the sequence of operations within mathematical limits, there are two systems that are most used. Division has priority in the second part, while multiplication still has priority in the first part. Such an equation would not be taught in today’s classroom. That’s why it will cause so much debate. Of course, computers cannot give the answer either.
