I've seen the reasoning for the banana thing because "that's how other primates do it so clearly it's the right way!!!" But I saw orangutans eating bananas in Borneo and they just tore the sides open with their teeth then smooshed all the inside into their mouth in one bite. I wanna see a life hacker eat a banana the orangutan way.

That is pretty drat close to literally throwing the banana on the floor and eating it off the floor like a animal you piece of poo poo. should be pretty familiar for the garden variety lifehacker.

Chard posted:Just saw this over in the annonymous confessions thread, thought it would fit here as well: I actually have to do this just about anytime the subject comes up. For some reason the knowledge of which months have 30 days vs the months with 31 days has never solidified in my mind.  Actually came up at work recently when someone asked if anyone knew how many days a month had and another coworker was amazed that they didn't know the knuckle trick. I guess people just use Google now.

Start with your left knuckle as January, the space between pinky and ring fingers is February, ring knuckle is March, etc. All the knuckles are 31 days and depressions are 30 or less.

Thirty days has November. April, June, and September. Of twenty eight is but one. And all the rest are thirty one. Of course leap year comes and slays. Every four years got it right, and twenty eight is twenty nine.

To continue grade school life hacks: there's the multiple of nines trick. Stick out your hands like you're giving a double high five. Putting down n finger gives the digits of the 9*n number with the fingers up. So you put down your left thumb you get a four and a five. 9*5 is 45.

aardwolf posted:"Thirty days hath September, April, June, and November" I don't understand how memorizing a list is supposed to be superior to memorizing a pattern. They're both slower than remembering each month directly, and you don't have to actually poke your knuckles any more than you have to actually sing the rhyme out loud. All that matters is that you know the answer.

I don't know about you, but I've never been away from a power outlet long enough to find out how neat that might be. It reminds me of teachers trying to convince us as kids that we had to learn how to do advanced calculations entirely in our heads because you never know when you might be stranded on a desert island with no calculator and a need to know the square root of 6,457. Because that's totally a thing that happens.

Dylan16807 posted:Oh sure I understand that different methods are easier for different people. I think it's just nice to know different methods to work out things. Like, I still remember all of the times tables up to fifteen by heart, but I still use mnemonic devices for various biol things and like when people share any mnemonic devices for anything ever if I'll never use them again. I've always used the "30 days has September, April, June and November" for months, it takes a few seconds to recite in my mind and if I don't say a month it has 31 days, BAM done. Although I'm also a big dummy and use the thumb and pointer trick for remembering left and right sometimes.

Gorilla Salad posted:Because 3 is a factor of 9 - or is that No, he means you can also use the trick of 'add all the digits - if the result is divisible by 9, then the original number was divisible by 9', just like you can for 3. This isn't just because 3 is a factor of 9, because the trick doesn't work for 6. (though it might be because 3 is the only factor of 9, besides 1 and itself)

Just to be pedantic, it actually does work for 6 if the sum is both divisible by 3 and 2 (individually works, you don't have to divide by one then the other). I'd imagine that actually holds up for any number that can be factored into 2 primes, and probably even a wider range than that... I smell a mathematical proof, but I never bothered with those e: And since it wasn't brought up yet, you can also recursively add up the sum digits if you're dealing with a gigantic number. Sure, it's easy enough to glance at "12" if you're trying to figure out "93" or "255", but you could also take that 12 and make it 3. Likewise you could deal with the kind of numbers that are so long they don't even have official names and just keep adding up the sums. That trick might only work with 3, but again I haven't tried it out. Maybe if you stop recursively adding before you collapse the number smaller than the combined factors you're trying to figure out, but I don't know vvv: Ha, I love it, I proved myself wrong with a second unrelated thought. I remember there being some way to do it, but obviously I had the wrong idea there

The proof falls out of 9 being 10-1 in our base 10 system or 10 is 1 mod 9. For 3 it's similar since 10 is 1 mod 3. Also why it doesn't work for 27, the next power of 3. Other rules are: 4: last two digits divisible by four. 6: divisible by both two and three, or even numbers that follow the threes rule. 7: gently caress off 7 your rule sucks and is tedious 8: last three digits divisible by 8.

Dr. Stab posted:How does that work for 6? 12 is a multiple of 6. The sum of the digits is 3, which is not divisible by 2. It's the original number, not the sum of the digits, eg. 84 is even, 8+4=12, 1+2=3, so 84 is divisible by both two and three, and is therefore a multiple of six (6x14), because x*3 is equal to (x/2)*6, and if the result is an even number then there must be an even number of 3s, so x/2 will be a whole number.

I was looking for ideas to organize my lipsticks and found a list of poo poo. It doesn't look very comfortable but yeah ok?  This is sad and just reminds me of my hoarder grandparents, except they would unintentionally just dump magazines from 2003 and random mail from charities in their dish rack because dementia   Cheese graters are sharp and hurty. I would love to scratch myself while grabbing some earrings as I'm running out the door.  I'm 99% this is animal cruelty because even fish need environments bigger than the inside of a loving computer.  Forgot to screencap it but throw a loving hose on your loving door! Just embrace your inner ghetto white trash rear end and gently caress the HOA brah!!
