A simple mathematical operation that generates consensus at the local level has caused a battle of knowledge on the Internet.

in an old **math exercise** whose fame is revived every so often in networks, because **there is no consensus** about your result. The **mathematical operation 8/2(2+2)** attack again. How is it solved correctly?

It is a simple mathematical operation that apparently has no difficulty. **8/2(2+2)** It’s a primary exercise. But there are people who say that **the result is 1**others that it is **16**… and some more. Who has the reason?

In school we were taught that the **order of operations** is **parentheses, powers and roots, multiplication and division, addition and subtraction, from left to right**. With multiplication and division, and addition and subtraction, other things being equal:

If we apply these rules, we have:

- 8/2(2+2), that is, 8/2*(2+2)
- 8/2*(4)
- 4*(4)
- 16

He **result is 16**. Easy, right? Well it is not too much…

If it’s so simple, then… why is there **graduates in Mathematics** they say that **the result is 1**?

The reason is that in Spain and most countries, it is used **the PEMDAS order**explained above:** **Parentheses, Powers and roots, Multiplication and Division, Addition and Subtraction.

But in some places it is taught **the BODMAS order**that **gives precedence to operations where any parentheses are involved**. That is, first you have to remove the parentheses. If we apply this order:

- 8/2(2+2), that is, 8/2*(2+2)
- 8/2*(4)
- 8/8
- 1

**result is 1**.

Who has the reason? Well, according to the University of Berkeley… both results are fine. The problem is that **the operation is poorly formulated, it is ambiguous**. When there is ambiguity, **more parentheses must be added.**

If the person who wrote the formula wants you to **the result is 1** must write** 8/(2(2+2))**. And if you want it to be **16**then the operation is **(8/2)(2+2)**. In this way there is no room for mistakes, use the order PEMDAS or BODMAS.

A **Math operation**, **8/2(2+2)**continues to generate debate on the Internet, because it gives rise to **different results**depending on who you ask. But it has a unique solution… **if you reformulate it correctly.**
