social network

Mathematical example divided Twitter into two camps because of the different answers. Both are correct.

8 ÷ 2 (2 + 2) – the example looks like this, and it is composed incorrectly.

On Twitter, a popular mathematical example was gained that frustrated social network users who received different answers. However, it turned out that the first and second are right, and the problem is the incorrect notation of the example.

Subscribers, count

In the subscriptions, subscribers were divided into two camps – some got 16, and the others – 1. The first immediately began to mock the second and advised them to improve their mathematics, while others answered the same. Even calculators showed different answers.

Everything except 1 is absolutely wrong.



First, I calculated in parentheses, then multiplied, then divided, so I got 1

It turns out 16, oh, replai just ashamed to read …

The answer is 1. Everyone who speaks 16 must retake math

Obviously, the answer is 1

It turns out 16, if you say something else, then start unpacking your clown shoes

The answer is 100

Some of you have failed math

I have never seen anyone as confident in the wrong answer.

Never seen anyone so sure that he calls the right answer wrong

Some even began to quote their academic degrees and the number of courses studied as evidence that their answer was the only correct one.

I have two degrees in mathematics, the answer is 1

I took 3 courses on computation, differential equations and linear algebra, it turns out 16, bro

The discrepancy in the answers was due to the fact that some users multiplied at first, while others, on the contrary, shared.

As a result, Twitter users decided that everyone got different answers depending on what order of calculations they learned in school. Those who first multiplied used the PEMDAS method with the following calculation order: first open the parentheses, and then multiply, divide, add, and subtract. Those who first divided and then multiplied, used BODMAS – in it multiplication and division have the same priority, and the calculations are performed from left to right.

If you count by PEMDAS, then the answer is 1. If by BODMAS, then – 16

With PEMDAS, multiplication and division have the same priority, you need to calculate what comes first from left to right. The same goes for addition and subtraction.

Since one part of the world uses PEMDAS and the other BODMAS, algebra can sometimes become confusing.

However, in fact, the problem lies in the notation – the authors of the example forgot to put brackets, so there were two correct answers.

Both 1 and 16 are correct answers, because the equation notation is incorrect. Can you finally shut up now?
