EXPLORE FURTHER: Reserved for the brightest minds! Can you tackle this seemingly easy arithmetic problem?
The internet is buzzing over a seemingly simple math equation that has unexpectedly stumped thousands of people.
Initially, the issue seems straightforward enough.
However, numerous users on X, previously known as
Twitter
, swiftly interjected with responses, but only a few managed to get it right—because only those recalled applying the proper sequence of operations.
To correctly address this type of equation, adhere to the PEMDAS rule—a basic principle usually introduced in fifth or sixth grade as part of the Common Core Curriculum.
PEMDAS stands for the order of operations when tackling mathematical equations. Start with what’s inside parentheses (P), then handle exponents (E). Next, perform multiplication (M) and division (D) moving from left to right. Lastly, carry out addition (A) and subtraction (S) also proceeding from left to right.
Let’s now examine the equation that led to all the confusion.
Try solving it yourself before reading ahead:
19 – 4 + 1 = ?
Many people ignored the rules and solved the equation strictly from left to right, which led to the most common incorrect answer: 3.33.
This error occurs when PEMDAS is ignored.
Utilizing PEMDAS, when solving the equation, you should begin with division as there are neither parentheses nor exponents present.
Start with dividing 12 by 3, resulting in 4.
The equation now changes to 19 – 4 + 1.
Starting from the left, we deduct 4 from 19 to obtain 15, and subsequently add 1 to reach the ultimate result of 16.

, failed to provide the right answer — resulting in an animated comments section filled with speculative guesses and assured misjudgments.
A user confidently shared ‘-16’ as their result, whereas another participant submitted ‘6.333333333333333’ as their final response.
Even though the mathematics involved are basic, this widespread incident serves as an amusing reminder that even straightforward challenges can cause confusion when we overlook fundamental principles.
The next time you encounter a math problem that appears straightforward, pause for a second, proceed cautiously, and allow PEMDAS to lead the way; this could prevent you from becoming an internet sensation for all the wrong reasons.
