“Easy Math Problem That Confuses Everyone | Can You Solve It Without a Calculator?”

Those “easy-looking” math sums that trip people up are usually written in a way that hides the real trick — mostly because of order of operations (BODMAS/PEMDAS).



Let’s take a classic example:

                                                                8 ÷ 2(2 + 2) = ?

At first glance, it looks simple, but people argue over whether the answer is 1 or 16.


Step 1: Solve inside brackets

8÷2(2+2)=8÷2(4)8 ÷ 2(2 + 2) = 8 ÷ 2(4)

Step 2: Handle multiplication/division from left to right (BODMAS rule)

Now we have:

8÷2×48 ÷ 2 × 4

Division and multiplication are equal priority, so we go left to right.

(8÷2)×4=4×4=16(8 ÷ 2) × 4 = 4 × 4 = 16

Step 3: Why confusion happens

Some people mistakenly read it as:

8÷[2(4)]=8÷8=18 ÷ [2(4)] = 8 ÷ 8 = 1

This is because the notation 2(4) looks like it’s glued together, leading people to treat it as a single denominator.


Correct answer (by conventional rules): 16
Wrong but common answer: 1


✨ Moral of the story: Even simple sums can confuse people if parentheses and operations aren’t crystal clear. That’s why math teachers always emphasize BODMAS/PEMDAS.

    1. Because I made a typo and there's no option to edit it, so I had to delete and write it again, without the typo

  2. "Now we have: 8÷2×4". No, you have 8÷(2×4). Refer to Maths textbooks... https://dotnet.social/@SmartmanApps/110897908266416158

    1. "That’s why math teachers always emphasize BODMAS/PEMDAS". Yep, and 2(4) is the P in PEMDAS and the B in BEDMAS. M is for Multiplication Signs, of which there are none in this expression. signed Maths Teacher

    2. If you want to thank me then either take down this misinformation or fix it to be correct. Some people will read it but not read the comments and see that it is wrong
