An apparently simple mathematics question has ignited an argument on the internet, causing social media users to scratch their heads in bewilderment.
The seemingly straightforward equation usually assigned to a fifth-grader has become widely popular after being posted by user @BholanathDutta on X (previously known as
Twitter
).
He shared an image of the equation with the description: ‘Can you FIGURE THIS OUT? #math’.
The issue at hand? 10 × 2 ÷ 4 − 2.
A simple computation is causing confusion among some users, as commentators are boldly sharing conflicting responses.
‘The solution is simply 3; you can calculate this mentally,’ stated one user, appearing rather unfazed by the task.
Certainly, most commentators concurred that 3 is the accurate solution—although some assertively maintained the answer was indeed 10.
Let’s now examine the equation that led to all the confusion.
What then is the right answer?
To resolve this, you must adhere to the conventional order of operations—often recalled using the acronym PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction).
Others might have studied it as BODMAS (Brackets, Orders, Division/Multiplication, Addition/Subtraction).
Nevertheless, the calculation has to be done following a particular order.
Make an attempt at solving it on your own prior to proceeding further:.
Initially, carry out the multiplication: 10 × 2 = 20
Next, perform the division: 20 ÷ 4 = 5
Lastly, perform the subtraction: 5 − 2 = 3
As per what math specialists say, the accurate response is actually 3.
The misunderstanding frequently occurs when individuals overlook the correct sequence of operations and solve equations from left to right instead.
To accurately resolve such an 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 as an abbreviation indicating the proper order to tackle mathematical equations. Begin with parentheses (P), proceed to exponents (E), continue with multiplication (M) and division (D) moving from left to right, and conclude with addition (A) and subtraction (S), again progressing from left to right.
