We all make mistakes. Sometimes, they’re really simple ones because we were tired or distracted. Unfortunately for these 50 people, the internet couldn’t just let it go.
The next time you’re about to post some math online, check your numbers before hitting that button. It turns out that there is an entire subreddit dedicated to people who didn’t do the math quite right.
Here are our favorites:
#1 Very wild
Either that math is wrong, or they know something about time machines that the rest of us haven’t learned about yet. Hey, you never know.

#2 Eat cheap
Well, someone messed that up. At least customers will benefit from the wonky math.

#3 COVID math
There’s something a little off about that social distancing math, but who really stands exactly 1.5 meters apart anyway? Let’s just go with “close enough” and call it a day on this one.

#4 Disorder of operations
The order we put numbers in does matter. He might not have been paying attention in class the day the teacher went over that.

#5 Can I buy those separately?
There’s a small problem with their math. Don’t worry. Everyone on Facebook will correct them.

#6 Pregnancy math
Well, there goes the theory that pregnancy is around nine months. Now, it’s a year or less than a month.

#7 Dollars and cents
Multiplication can go wrong, especially if the decimal is in the wrong place. It’s best just to check the end result and make sure it actually makes sense.
Or you can just die a little inside after realizing your error.

#8 It’s that time again
Well, 20:20:20 happens every night. We’re not sure what date they wrote that on, but there’s also no 20th month.

#9 Getting rich
They may have messed up the math a little. All those zeroes can get overwhelming sometimes.

#10 Oops
People are quick to correct each other on the internet. Just double-check your math before you make that comment.

#11 Increasing population
Maybe they had 500 million tourists? Yeah, we don’t really think so either.

#12 Hm
Redistributing spending is an interesting idea. However, the math doesn’t always work out.

#13 It’s the principle
She wanted to save a little money. That’s not quite how it worked out.

#14 Embarrassing
That was just bad. It had to be a joke post. Right?
Source:
tonyoncoffee via Reddit
#15 A little harsh
The person responding could have just pointed out that the math was wrong. Then again, they did manage to rhyme.

#16 Where to begin
There are so many things wrong here. Where do we even start?

#17 Billions!
Math is hard sometimes. We do wish they were right…and that someone was handing out billions.

#18 Competition
Losing sucks. However, this is just adding insult to injury.

bougieprole via Reddit
#19 So close
They just need a couple more quarters. Maybe they were tired that day.

BFGypsy via Reddit
#20 Basic multiplication
It started out well. Unfortunately, multiplying by zero will never put anyone ahead.

Jamo999 via Reddit
#21 The median
Do you ever feel like people over-explain things? Like when they have to explain that figures will fall both above and below the median.

#22 Failed logic
That’s not how aging works. That’s not how many things work.

ivan200520052005 via Reddit
#23 Almost
A hundred million, a billion… What’s the difference, anyway?
Source:
dankmonkeyss via Reddit
#24 Hm
Are they confused? Are they joking? We have so many questions.
Source:
cckarate7 via Reddit
#25 Almost simple
Basic math is helpful. It’s just not the answer to every math problem.

pedicarete via Reddit
#26 More day
It starts out bad. Then, it gets worse. We didn’t even see that coming at us at 75 miles per hour.

EkskiuTwentyTwo voa Reddit
#27 They tried
At least they’ll get the right answer. That’s something!
Source:
shwifti via Reddit
#28 Not a genius
They thought they had beat the system. They may have been wrong.

lukeber4 via Reddit
#29 Kind of cute
You don’t need to be good at math to be good at love. That’s a fact.

#30 Not getting hired
There is no way they are getting the job, and it has nothing to do with their age.
Source:
dubnr3d via Reddit
#31 Impossible situation
What about the people who want to take advantage of the sale? Why even have the sale?
Source:
grrrr12344 via Reddit
#32 That’s not how addition works
Their addition is correct. The issue is that it’s not that kind of math problem.
Source:
LemurFemurr via Reddit
#33 Percentages
They were supped to take 50% off the price. Instead, they took off significantly less.
Source:
mavolvv via Reddit
#34 Wrong way!
It was supposed to be a rollback. This is clearly going in the wrong direction.
Source:
Seabass9975 via Reddit
#35 Almost
Someone tried to do a math problem. They just got a couple of things wrong along the way.
Source:
campbell-1 via Reddit
#36 Twenty-five percent
That tiny little corner is a lot less than 25%. It might be time to adjust that image a little…or a lot.

#37 Take two sets of 3s
It seems like a reasonable enough sale until you do the math. At that point, “buy 6 get 7 free” starts seeming a little less compelling.
Source:
budge198 via Reddit
#38 The longest flight ever
It’s no fun when you’re on a plane and can’t even properly stretch your legs. Finding out that the flight will take several days could only add to that pain. Thankfully, no plane has enough fuel to actually stay in the air that long.
Source:
justthetipping via Reddit
#39 Too much math
At least they tried. No matter what the numbers are, I think we can all agree that 2020 hasn’t been the best for a lot of businesses.

masterzeus2 via Reddit
#40 Plot untwisted
Who doesn’t like a good plot twist? Don’t let a little math get in the way!
Source:
Nogray02 via Reddit
#41 A bad sign
Sure, people on Twitter might get math wrong in conversation. But what about when it’s a company that sends you a monthly bill?
Source:
fly72 via Reddit
#42 Only a little off
We assume they just rounded the numbers. Otherwise, this just doesn’t make any sense.
Source:
Vagabond_Monk via Reddit
#43 Not exactly
Usually, when something is 50% off, we expect it to be 50% off. That’s not quite what is going on here.
Source:
nokatydidnt92 via Reddit
#44 Not too precise
Let’s hope that they don’t actually need precise measurements. If they do, this won’t end well.
Source:
dj_ordje via Reddit
#45 1/900th of an Avenger’s movie
Maybe they added in an extra zero. Something went a little wrong here.
Source:
Manduli via Reddit
#46 Costs
Their heart may have been in the right place. Their math could use a little work, though.
Source:
HamMan_42 via Reddit
#47 Heartbreak
It would actually take a few days at that speed, but that’s still not great for a relationship. It was over before it even started.
Source:
goofyonlinepersona via Reddit
#48 A troll?
The name seems to make it seem like they’re probably a troll. Then again, we’ve seen math that bad before from non-trolls. Sometimes, it’s just so hard to tell.
Source:
travradford via Reddit
#49 Amazing deal
We all love a good sale. In this case, the store manager might be loving the sale more than we are.

#50 Free plates are expensive
The word free can be tempting. The price for a “free plate” might not be so tempting in this case.
