Learn about simple math that even ChatGPT has missed

Humans’ desire to test their wits in small challenges never gets old. One math calculation That spread in 2019 once again divided the Internet between two possible explanations and outcomes of the operation.

Modernity, this time, not even chat He escaped from the quarrel.

What is 8 ÷ 2 (2 + 2)?

The equation is small and the numbers are from the most basic levels of the tables. However, those who think the decision is simple are wrong.

Many netizens came forward saying that the answer is 16. As an argument, they even published chats with ChatGPT Twitter. Is this correct?

We decided to test it by asking the bot artificial intelligence Confirm your answer. a ByteChatGPT changed its mind and explained that the answer is 1.

which one is correct?

Everything depends on the way the operations are done. One of the well-known rules of mathematics is that you must solve what is in parentheses first. In this case, “2 + 2”.

Having done this, we are left with the following expression: 8 2 (4). This is where things get complicated.

• Whoever decides to divide 8 by 2 first and then make a 4×4, has 16 left;
• Anyone who multiplies 2 by 4 and then makes 8 8 has 1.

Mathematicians claim that the latest conventions adopted by mathematics determine the method of computation.

The abbreviation in English PEMDAS indicates that the order to be adopted in operations is:

• bows
• preachers
• Multiplication and division;
• Addition and Subtraction.

All this must be done in the order in which the processes appear, that is, from left to right. So the first answer is correct and The score is 16.

Presh Talwalkar, a mathematician trained in Stanford, USA, explains on his YouTube channel why even calculators can get math wrong. The binary decisions made by the system can follow the most common order of operations or they can have their own order, defined by each developer.
