Weโre all human here, right? So we all understand that sometimes, our brains just donโt want to work. Yes, we know what two plus two is, but sometimes we just have a โderpโ moment. Thatโs because weโre not robots!
That being said, just because itโs normal doesnโt mean itโs not hilarious when other people mess up. There have been several times when people have had brain farts โ which weโve gathered here โ and every time, they were so funny.
Get ready for some big belly laughs with these โoopsโ moments!

1. So closeโฆ
โฆYet so far. This person thinks that 3000 โ 2020 is 80 but itโs actually 980. I donโt think anyone whoโs alive right now is going to see the year 3000.

2. Back to school it is!
โ$1,000,000 wouldnโt be enough to fix this personโs education,โ someone hilariously commented on Reddit. We donโt want to be too mean butโฆ That is pretty dang funny.

Reddit
3. Yikes
This one has a lot of people on the Internet losing their mindsโฆ Is it satire? Is she serious? We want to believe itโs a jokeโฆ But in todayโs world, you just never know.

4. Exceptโฆ
Exceptโฆ This actually will happen again. It will happen over and over again, every single night for the whole year.

Reddit
5. Itโs simple math, really
This person wanted to burn a guy with mathโฆ Itโs too bad he canโt actually do math, though. 0 x 500 is still zero โ facts!

Reddit
6. I donโt think thatโs the reason why you wonโt be hired
Just because they have a minimum age doesnโt mean they have a maximum age. If this person doesnโt get hired, it will be because of their IQ, not their age โ ha!


Source:
Reddit
7. Wait soโฆ
So this person is claiming that they are 190 years-old, correct? Because if they lived 19 decades then yeah, theyโd be 190 years-old.


Source:
Reddit
8. Are you sure youโre doing math?
This person said that people born in 2000 are 25 years. But that doesnโt make any sense because itโs only 2020, and this was posted a few years ago. Thankfully, this personโs response was perfect.

Reddit
9. For the 0.01th time?
The math is wrong, and weโre pretty sure everything else in this tweet is false, too. Not the most trustworthy source but at least itโsโฆ entertaining?

Reddit
10. Share your limited edition quarters!
This person must be using special quarters or something, because a dollar every day for a year only equals $365, and he thought a quarter every day for a year gets you $9,125. Nope!


Source:
Reddit
11. Worst sale ever
This sale is supposed to be 50% off but then weโre only getting around $2 off? Something isnโt adding up here (literally).


Source:
Reddit
12. Is your calculator broken?
Okay, this one is even stranger than the previous oneโฆ Where are people getting these numbers? Is their calculator broken?


Source:
Reddit
13. How does this work then
So you get 4 for $5, but itโs limited to only 3 per customer. The only way to take advantage of this sale would be to come with another person and split it up maybeโฆ But still doesnโt really make sense. Stop contradicting yourself, store!

Reddit
14. Butโฆ
But Americans are actually right! A mile is less than a kilometer. Simple math, really!


Source:
Reddit
15. An expensive free meal
This meal claims to be free butโฆ Thereโs nothing free about it at all. In fact, itโs quite expensive!


Source:
Reddit
16. Can you even disagree with math, though?
Yeah, sure. If you sleep a couple hours less, than you can have a 27-hour dayโฆ Weโre obviously being sarcastic here, by the way.


Source:
Reddit
17. So only 4% people wash their hands?
Weโre not sure this person is doing the right math, as they believe that almost 100% people wash their hands. Our brains hurt.

18. Tipping ainโt a city in China
Beth needs to re-do her math becauseโฆ This just ainโt right. Someone please tell her.


Source:
Reddit
19. What do they not get
How does 190 split up into a perfect 50/50? Easy: 190 divided by 2 is an even 95. Easy as that!


Source:
Reddit
20. Ah, proportions
โThe real problem is that he says they are 3/4 horse and the graph suggests that they are made out of 3/4 of a horse which I do believe are two different things,โ a very smart Reddit user commented.


Source:
Reddit
21. We hope they are kidding
Apparently 50 x 0 = 50 but 0 x 50 = 0? Obviously, this is just wrong. We hope they are trolling us. If so, they got us good!


Source:
Reddit
22. Didnโt see that one coming!
Just ignore the commentโฆ Theyโre trolling. It is a good reminder to never assume though!


Source:
Reddit
23. Ooooof, weโre not sure about this one
This person knows that you need to be pregnant for 9 months before actually having a baby, right? Apparently notโฆ


Source:
Reddit
24. We canโt tellโฆ
Is this dude trolling or just not that bright? He thinks he pulled off some major scam. We think he really just has no ideaโฆ Which is honestly hilarious.


Source:
Reddit
25. Ah, TikTok
This person thinks sheโs way closer to 1 billion followers than she actually is. 4 million plus 96 million is 100 million, not 1 billionโฆ Duh.

Reddit
26. A confusing pie chart
ABC did not do the correct math on this one. The total equals over 100% so yeah, definitely something wrong here.


Source:
Reddit
27. Another day, another confusing graph
Maybe if they are in 3D this could work. But right now, weโre not seeing how itโs going to go downโฆ


Source:
Reddit
28. Potentially a good deal
$90 for both or $40 for eachโฆ This could be a great deal โ if you buy them each separately, of course. That would make it $80 total, giving you an extra $10 off.


Source:
Reddit
29. Come together
Math isnโt always easy. Sometimes you need a little help. Itโs nice to see all of these people come together on the Internet to solve a very basic math problem.


Source:
Reddit
30. Broken calculator
If you do this going from left to right, it should come out to 10. But if you do it backwards it actually is 15. Needless to say, weโre all confused.


Source:
Reddit
31. Someoneโs saving moneyโฆ
But itโs not us. Originally sold for $299 but on sale for $324.99? Somethingโs not right here, but our brains are telling us this is the worst deal ever.


Source:
Reddit
32. Worst motivational poster ever
This is actually making us cringe. Also, shouldnโt this man know how compounding interest works?


Source:
Reddit
33. I mean, yeah
Weโre pretty sure everyone feels this way, with or without love, because 60 minutes does indeed equal on hour. We bet this guy doesnโt know that 60 seconds is equal to one minute, either.


Source:
Reddit
34. Oooof
โI donโt even like math but thatโs straight up disrespect,โ someone commented on Reddit. Sadly, weโre going to have to agree with that statement.

Reddit
35. One gram = 15 grams
According to this guy, at least. Is someone going to tell him? Or should we let him carry on through his life believing this lie?


Source:
Reddit
36. Only off by 100xโฆ
Weโre not really sure how someone can mess this up so bad. Sometimes it feels like people mess it up on purpose? Itโs the only way itโd make sense!


Source:
Reddit
37. But(terfinger)โฆ
But 25 calories multiplied by 6 pieces is 150, not 140. Do we get a calorie discount if we eat more of them? Weโre not complaining, we just want to understand.


Source:
Reddit
38. Interesting sale
Weโll take two sets of 3 then, by the looks of this very interesting sale. Weโre curious, whoโs in charge of coming up with these deals? We just wanna talk.


Source:
Reddit
39. We canโt even trust math teachers
This a math question. The answer isnโt even wrong, but the question is. Quick, someone hold me back.

Reddit
40. Flight from Hell
Imagine being on an airplane for 135 hours? Obviously, somewhere along the way, this math got messed up. That, or they just flew around the world nonstop for fun.


Source:
Reddit
41. That is not how it works
Weโre surprised this business-based media company isnโt better at doing math or pie charts. Actually quite scary!


Source:
Reddit
42. Makes sense!
Weโre sure these people can make it work. Theyโll just need some rockets traveling at the speed of light and some time traveling capabilities. What?


Source:
Reddit
43. Help
Time divided by distance gets you units of distance over time? We are so confused. Help.


Source:
Reddit
44. Weโre all winners
According to this guy, we should all be winning millions of dollars! This is a rare case where I actually wish he was right. The lottery would be so much better that way.


Source:
Reddit
45. That canโt be right
Fox claimed that 500 million people in North Carolina were without power. The problem here is that there are only about 10.5 million total people in NC. Soโฆ weโre not sure where they pulled these numbers from.
