Math problem leaves the internet scratching their heads

In recent years, several math problems have gone viral, sparking widespread debate and confusion online. One such problem that particularly stumped the internet is:

Problem: What is the value of 8 ÷ 2(2 + 2)?

Solution:

To solve this, we must adhere to the order of operations, commonly remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

Parentheses: First, simplify the expression inside the parentheses:
- 2 + 2 = 4
Multiplication and Division: Next, perform multiplication and division from left to right:
- 8 ÷ 2 = 4
- 4 × 4 = 16

Therefore, the correct answer is 16.

This problem gained significant attention on social media platforms, with many users arriving at different answers due to varying interpretations of the order of operations. A Twitter poll revealed that approximately 39% of respondents answered 16, while 59% answered 1. citeturn0search2

The confusion stemmed from the ambiguous formatting of the expression. Without clear parentheses, it’s challenging to determine the intended order of operations. This highlights the importance of precise mathematical notation to avoid misinterpretation.

Another viral math problem that puzzled many is “Cheryl’s Birthday,” a logic puzzle that went viral in 2015. In this puzzle, participants are given a list of possible birthdates and must deduce the correct one based on a series of clues. The problem gained widespread attention and sparked discussions about logical reasoning and problem-solving strategies. citeturn0search5

These viral math problems underscore the importance of clear communication and understanding of mathematical principles. They also highlight how mathematical puzzles can engage and challenge individuals, leading to widespread discussions and debates online.

In conclusion, while math problems like 8 ÷ 2(2 + 2) and “Cheryl’s Birthday” may seem straightforward, they can lead to significant confusion without proper notation and understanding of the order of operations. These puzzles serve as a reminder of the complexities inherent in mathematics and the importance of clear communication in problem-solving.
