That trick is quite good, ive used it i a few situations. but it kind of only works on numbers near 100. i mean if you were to try this on like
72*76, you have to know what 28*24 is in head, so then its kinda contraproductive, sice there is also en easy way to calculate 11*11 to 19*19.
this trick is only necessary up to the difference on the highest multiplication you know in head.
if you by a second can do 28*24, then you ofcourse hav a wider range.
so what i should say is, that this works up to the range if small multiplying you know.
if you know 1*1 to 20*20 then the range is 80*80 to 120*120.
what i also suggest is to cover 1*1 to 20*20, 30*30 to 70*70 and the trick you mentioned.
Still there are some combinations left , but i covers much more than the averge person knows.

great tips, for all swedes there are books which helps with these things.
dunno much about english books on the subject.

That means you needed something to make that one work that wasn't in the original.
We were taught this at a very young age as a way to check if an answer was correct because it isn't 100% with all numbers but comes fairly close. Still, not a life hack.
however according to the shitterton method its
it is simply false. unfortunately people hear about this shit on FB and think its real then get small calculations wrong for the rest of their life because of some psudoscientist who can draw a convincing picture
Hmm, I can half it also:
35*43 as was the original test:
you use 50*50:
50-22=28 but cause halved 14 or 1400 because the first part of the answer.
This is actually incorrect, only newer (2010+) vehicles can run on water + gasoline
Ever since I discovered this my life has been so much better
ok, you have misunderstood it.
the method that OP uses compares the numbers to 10 000.
because 90*90 to 99*99 are close to 10 000.
so 70*70 would be. 10000 - (3000+3000) + 30*30 = 4900
OPs example is same 10000 - (3000+4000) + 3*4 = 9312

Plugs keep bending? Move to Britain.
no im not. that is the idea behind the trick OP uses. it a general rule, but it fits best to products near 10 000. numbers near 50 can be compared to 50*50 (2500) in the sam way.
but if the difference is too high you knid of lost to point.
13*18 is also possible to calculate with the method but you have to know
very high products, so its contra productive if your goal is the calculate it
in a few second which these tricks are invented to be...
protip: learn math
and apparently you can choose the region based on the numbers, for example 14×16=224 so we choose 20x20, ie. divide by 5:
20-(6+4)=10 divided by 5 = 2 or 200
6×4 = 24
You dont have to use 100×100 since the numbers are not close to 100 but choose the limits close to numbers.
dude, you abandoned the thread already so please leave as we are discusssing this. This is the first time I've heard of the method and I'm putting it to test and it seems to work.
The method tells you to subtract the sum of 30+30 from a 100, ie. 100-(30+30)=40 like 100-(3+4)=93 then multiply 30×30=900 like (3×4=12).
53 is a motherfucking awful idea.
You never ask someone out in front of an audience, if you get rejected it's like 10 times worse. And if she said yes, she'll flake if she isn't really interested. Just talk to her when you two are alone, and be straight up.
And don't let rejection phase you, play it off like a joke. People can change, and she might come around sometime.
i never used this method and never will.
it was just a pic to bump the thread.

i dont know. we have borrowed many word from english.
like every word that ends with -tion is the same, but different prononce.
so in many cases you can figure out the words.
but still, its a strange language with strange sounds and letters
åäö ÅÄÖ. its feels like the basics are different but the more complicated words you learn, the more likely is it to be in the enlish language.
also we dont have the word "the". instead we use suffixes.
a - an, is hard in swedish cuz its no genreal rule, you just have to get the feeling.
Yes it does, check my old post...
you just dont understand whats actually is going on.
50*50 = 10000 - (5000+5000) + 50*50
its looks like troll, but 50 is a really easy number to use here.
40*40 = 10000 - (6000+6000) + 60*60 = 1600
use desitin overnight to clear your face. when you wake up in the morning, your acne will literally fall off in the shower. your face will bleed for a few minutes, but not nearly as long as if you'd just ripped it off. do this nightly, as a lot of acne still exists under the surface. just leave it on while you sleep.
a lot of people don't get nearly enough fruit. I'm surprised when I See that some people only eat a banana every day or so. so what you need to do is buy a bullet blender and make smoothies.
>a handful of grapes
all that in one glass, and it tastes amazing. by mixing the fruit with each other, and with ice, it convinces your brain that you are having something unhealthy because of its taste. after awhile you stop craving junk food and start craving a smoothie, so it both helps you eat healthy AND avoid junk. i have one every single day.
>reading through it
>slow reader, takes me a while
>fuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuucking shit i cant trust this information i spent 10 minutes reading
Fruits like apples and bananas are excellent foods that trigger the release of dopamine. Bananas contain an amino acid called tyrosine which is the most important stimulant for the brain to produce dopamine. The brown spots on the banana contain the highest amount of dopamine. NaturalBuy.com explains that adding bananas to a diet may helps treat symptoms of depression. Apples contain an antioxidant called quercetin. Quercetin works to preserve dopamine levels in the body by protecting the dopamine cells from getting destroyed. Other fruits trigger the release of dopamine are blueberries, cranberries, prunes, and strawberries.

Seriously, is that picture too hard for you to understand or can't you do basic math?
They do it in industrial microwaves as well. As long as the electrical signals can not arch the microwave will not discharge electricity into the spoon. In other words don't put two spoons in the microwave. One is fine. DO NOT put foil of any kind in the microwave. The creases allow for the electricity to arch.
motha fuckin nerd. but im laughing alot cos im baked
Is anybody ever so stupid to mix chemicals from a guide found on /b/?
If you found a guide on /b/ saying to mix cola and whisky to make whisky-cola, I probably wouldn't trust it.
The books are in swedish. i dont know if he has translated them to english or other languages, if so, you can read them too!
the books are about bodylanguage and what we really mean when we do different things.
Elementary, my dear Anon. You grab a magnet and drag it across your PC and monitor.
Only learn prime times tables past 9. They can be factored and made easier. I practice all the time by factoring 3digit #s you only need to know up to 31 to get to 1000 -super math nerd
Not even the same anon. Was saging, but check IDs. I'm not IOHosqgF just sick of dumbass "autism autism autism" accusations all over /b/. You fucking idiots need to pick up a dictionary.
The problem with this is that they are all too specific tips and it only works/happens under specific conditions.
An approach on the most fundamental patterns of human behavior, maybe coming from the evolutionary psychology perspective are way more effective and you have way less work in adapting yourself.
Smiling is a sign of submissiveness and it's sexy for a woman, but not for a man. It makes him look friendly and incapable to harming anyone.
