i didnt get the meme. pls someone explain
It’s a simple equation. But out of habit and not wanting to get it wrong, we type it into a calculator just to be sure, but it makes you look dumb, so you look around to ensure no one thinks you can’t do basic math
lol okay now I get it! who doesnt do that? but not with simple additions. Well, 4 * 8 is 32 …right?.. right? checks calculator
I have dyscalculia. Don’t tell my boss though as I have made mental calculation error several times and he had been angry because it would look bad on reports. Good excuse for me to use the calculator, though, without any judgements.
I have it too. Never got a solid base in math.
Doing fine though. I can use excel and a calculator and basic programming so it’s fine . I just cant do long division on paper
sounds like the counts real surname. makes sense why he’s constantly counting out loud.
I’m not embarrassed by my browser history but I’d die if someone found my calculator history.
This is a solid expansion on the meme tbh
Mental math tricks are important.
Take 2 from the 7 and give it to the 8. You now have 10 + 5. Much easier math.
Take 2 from the 7
Hold on, I just need to check something. Looks around nervously
Yes, that seems easier to me as well! I was not allowed to do this according to the teacher when I was a child. They wanted me to do it in some weird counterintuitive way. But I was very stubborn and I am still doing calculations in this way. She is not the boss of the way I think!
Why would you just type 15 into your calculator?
I once typed in 1+1, though it was several term equation and I was mentally reducing each term before punching it in.
I don’t know what to make of this comments section. This many people really don’t have 8+7 down?
I don’t even feel superior about it, just bewildered.
Yeah, I thought there was something more to it and am disappointed.
Maybe I just have it fresher in my head because I play a lot of Killer Sudoku. 15 pair box? That’s a 7-8 or a 6-9.
Same here. I wasn’t great before, but I’m actually super fast at anything below 45 now.
For us older folk, and unfortunately, also for some younger folk that grew up in more “conservative” small towns, borrowing and fancy math trickery was the work of the devil.
We were required to memorize the addition tables as well as the multiplication tables. And even then, addition could be done on your fingers and toes so as long as you could add the big numbers like 8 & 7 together faster than the really slow kid could take off his shoes and work it the hard way, you were considered proficient at addition.
So ya, there’s a wide swath of America that just sucks at basic math.In my case, the mental math trick suggestion (make it 10 + 5) was intended as a way to build a skill using the provided, easy example. That type of mental math can be applied to much larger numbers, particularly when combined with other mental math tricks.
In high school calc, I would do all kinds of algebra, integration, etc. and then at the end add 8 and 7 and get 13. All the time.
To this day, put 7 anywhere in my equation and I am gonna return an error. Dunno why. Remove 7, I work, give me 7, I suddenly struggle a lot.
Must have been doing a lot of base-12 math?
Its like when you do the whole logic and calculations part and then forget to square root the number at the end.
I’d always forgot to change signs after multiplying
Don’t you just carry the 1?
1 calculator app on my phone, always.
I can barely carry myself, don’t expect me to carry numbers.
I actually never learned this (terrible math skills from never learning basics)
Is that just adding 7+7 and then 1?
I was just being dumb.
But 8-7 DOES leave you with 1. And if you carry that 1…well. You get the picture. The possibilities are endless.
No, it’s Carry On My Wayward Son.
All it means is I got 141 2/3 chance of winning at Sakerfice.
This is why learning binary is so important. In base two, the same equasion is 1000+0111=1111, now you just convert back to decimal with: 8+4+2+1= sweats and starts counting on fingers before reaching for calculator
Easy, just convert to hex, 0x0F
Neat trick, now do nonary!
Right, as we all know, the most sensible way to do nonary algebra is in ternary, so we simply calculate 22+21 and convert back to nonary, and optionally decimal afterwards. So, 2 add 1 is 0, carry the 1, add it to 2 for 10, add the 2, carry the one, pad to 4 places and we have 0120, or 16 in base 9. Now to convert to decimal… removes shoes and socks
I am chronicly paranoid because I have had a low battery on an exam. I just type in simple math because it might be totally borked and you won’t catch it on something complex
Wait, it gets things wrong on low battery?
I can’t speak for low battery, but I can for different brands of calcs.
Back in high school majority of students had this specific model, and I had a different one. My entire answer to a question on an exam was correct, but my calculator somehow calculated different decimals to the ones from the popular model. And it was like 4th, 5th decimal or something. The asshole teacher took all of my points away on that. Meanwhile, one of her fave students forgot a very important part of the formula which made the calculation completely wrong and the teacher still gave them half the points for it. God, I hated school, lol.
It…shouldn’t. The 7-segment displays will have contrast issues, then the whole thing will stop working entirely when the battery gets too low.
Same. In contexts where there are a lot of already taxing elements, there is just no mental bandwidth for switching gears and doing the calculations. So calculator it is. I do find it important to hone my skills from time to time, just not to lose them.
For me it’s 8+8-1 since the doubles are memorized
This is the same for me, but I did 7+7+1, basically
So, for me it is 10-8=2. Then 7-2=5. And then 10+5=15.
Okay I know it’s 15, simple math, after all 8+8 is 16, you would have to be an idiot not to know that, so it’s just 1 less than that, anyways let me pull out my calculator just to check…

Now do it where you turn all the numbers into ones via math fuckery

8+7
11+1+1+1+1
that an 11
oh i know that one from my cribbage days
I just say I’m not good at math while i look at someone in the eyes for a little while until they do the math.
