TIME TRAVEL POWER! Ultimate Nerd Version.. Your Power is literally setting a save file. You can only save up to three separate save files at one time... By going back to the oldest save file you delete all other later save files.. when you go back to a save file you continue on from that point. best superpower though.. that id like.. I'd want the power to "level up" via an EXP system UI that only i can interact witth and use.

When my math teacher taught the PEMDAS she said that it could be more accurately described as PE(MD)(AS) since the multiplication/division and addition/subtraction have the same weight respectively

Another way to reach 16: 8/2 can be written as a fraction, 8 over 2. 4 can be written as a fraction, 4 over 1. 8 over 2 multiplied by 4 over 1 is 32 over 2. Simply to get 16 over 1, which is the same as 16.

Apart from being correct the first time I solved the equation *dabs* I found that a good way to explain it to my friends who didn't get it was to treat it similarly to quadratics (I think that's the term), in that I went 8/2 = 4, so it's now 4(2+2) then did 4x2 +4x2 which is 16, circling round to my original answer.

Sebbgaming5 hari yang lalu

It's 16 because when you solve the equation you have to go left to right.

18:32 We can't smell the basic metals themselves, but the smell you might resemble metals by is infact the metal's chemical reaction with bodily oils or other impurities on the metal (e.g. after touching it wih your fingers you leave some oils on the surface etc.) ...point is you smell a composit molecule that is made from a reaction with the metal, not the metal itself. Nile Red on IDreporter is testing and explainging this in much more detail if you are interested in that:P

Didn't bother to watch a 30 minute video on a second grade math problem, but I will ease all your minds and tell you that the answer is 16. Unlike the dress where the human eye can perceive colors differently, math is an exact science. There is no debate. When you have multiplication and division in the same problem you go left to right. The first 2 in the problem lies outside the parentheses. Where is the confusion?

Pheldagriff6 hari yang lalu

I don't care wether this is wrong or not but if this were written 8 / 2 * (2+2), I would interprete it as 16. but given that there is NO multiplication mark (which can be rightfully omitted), I interprete it that the (2+2) belongs to the outside 2, leading to the answer 1.

40Kfrog6 hari yang lalu

No. Conventions are arbitrary and have no bearing on the actual correct answer. It's either 8/(2 x(2+2)) or (8/2)*(2+2) and you CANNOT claim to have the correct answer until you get more information and determine which one.

I know this videos old and you guys probably won’t see this, But the more I think about it the more I think I’m gonna delete my social media after watching this. As I think about it, I realize it truly does fill the “boring” parts of my day. Literally just like a bad filler in an anime. Thank you guys for putting it into a bit of perspective and making me think about it more than just “eh it’s entertaining”

rob bowman6 hari yang lalu

I’m sorry, the way that you have it written there implies it is 8 over 2(2+2), meaning you would do the multiplication first because they are all in the denominator. If you use the division symbol, not the slash mark, that would make you correct, but the slash implies fractions.

Jared Bergsma.6 hari yang lalu

I like to convert all divisions into multiplications. So I read that as "8*0.5*(2+2)" so no matter how i do it i get 16

Drew Lehman6 hari yang lalu

That and the way computers process data, they treat the 2 as the single variable being divided into, you HAVE to put more parenthesis to include more operations or an expression under that division, unless you input a variable that is itself a function but it is contained within that variable so you don't even see the operation, just (#)/f(x)

lordchaos77706 hari yang lalu

All you gotta do is replace the / with ÷ and isnt 8÷2(2+2) easy to see how you get 16?

Eric Hillmeyer6 hari yang lalu

Even if you did the equation out of order of PEMDAS, i.e. simply going left to right, you get 16. You start with 8/2, which is 4. Then, since you parentheses aren't a multiplication star or dot, you do what's in the parentheses (2+2), which is 4. Then, you continue on left to right, multiplying 4*4, which is, as we already know, 16. Granted, knowing PEMDAS is useful for allowing you to quickly and efficiently do equations without a calculator, but even without it here you don't get 1.

Patrick Keller6 hari yang lalu

Sry Kale but you missed one detail in this: the multiplication is contracted, the opperator excluded. Consider this difference: 8 / 2X 8 / 2 * X

Harry Townsend7 hari yang lalu

A lot of teachers will not tell you about the left to right rule. A lot of teachers will mention it but will complacently let kids forget about it and blindly follow PEDMAS.

Just gotta say on your point of Facebook or a phone carrier selling your data “illegally” or “without your consent” they 100% have your consent if you signed a contract or hit that “I accept” button... Facebook would not make money if it didn’t sell data so either they sell your data cause you clicked “I accept” and continue to use the platform or you quit Facebook and they shrivel and die (in a business sense not literally die)

Isn’t it “PEDMAS” , I believe that is what I learned in school. I could be wrong though

Andrew Stalker6 hari yang lalu

It doesn’t matter what mnemonic device you learned. They literally all mean the same thing. It’s the order of operations. It’s the same everywhere.

Hi Kyle, The equation written online is 8÷2(2+2), using the obelus (÷), which historically means 8 over 2(2+2) as shown below 8 ------- 2(2+2) Now there are two ways you can break this down. Using the distributive property, which occurs before PEMDAS www.khanacademy.org/math/pre-algebra/pre-algebra-arith-prop/pre-algebra-ditributive-property/a/distributive-property-explained So 8 --------- (4+4) Or you can reduce common factors 8 divided by 2 and removing the 2 from the bottom of the equation. With that you have 4 ------- (2+2) or more simply 4/4 Which is 1. So there are two ways to show getting the answer as one getting 16. Now if you plug it into a calculator, sure, it might give you 16, but that's strictly doing PEMDAS left to right. However, that doesn't mean it's correct. Some years ago I took one of these controversial problems plugged it into Google and another math calculator and got two different answers. It depends on if the calculator sets up the problem correctly, or strictly does PEMDAS left to right. So, I object to your answer that 16 is the correct solution for the equation and raise you 1, good sir.

How would you calculate 8/2a where a = 2+2?

J W8 hari yang lalu

While i can see where you are coming from this, it is inherently incorrect. The division symbol of "/" is not the same as "÷". If this equation read: 8÷2(2+2) you is correct, however the symbol "/" represents more than just pure division of one number of the other. The "/" represents a value called the dividend (in this case 8) and a divisor (in this case the representation is 2*(2+2)). I disagree with the assessment.

Regarding neural link, there is one application I am rather hoping will get explored further. There is some hopeful progress in allowing disabled people to link to their prosthetics (either internal or external) through neural link, which might make it possible to restore some form of basic sight to blind people, basic hearing to deaf people or restoring motoric function through exoskeleton or implant to people unable to use their limbs otherwise. That would definitely be a worthy use of neural link to me. I know for fact some minor successes were achieved using this method to restore some basic hearing. The brain is wonderfully flexible and seems to be capable to interact and learn to use the stimulus from external aides.

Austin Reeves8 hari yang lalu

So you can start division while the parentheses are still there? 8/2(2+2) does not mean 8/2*(2+2). 8/2(2+2) goes to 8/(2*2+2*2) which is distribution (part of parentheses). We then follow PEDMAS inside the parentheses so multiply/divideing means we get 8/(4+4) then we follow up with addition/subtraction leading to 8/(8) the number in the parentheses is now complete since PEDMAS is complete inside the parentheses and only a symbol is touching so remove the parentheses. we now have 8/8 there are now no parentheses so we move on to multiplication/division. We now have 1. Also the / symbol indicates a fraction and not division. If you want to get 16 the equation would have to be 8÷2×(2+2). 2×(2+2) may seem redundant but it is required to have the 8÷2 come first

Sami Kay8 hari yang lalu

This could have all been prevented if they also put parentheses around 8/2.

HKVeteran8 hari yang lalu

Regarding the equation, I was taught to look at division as an improper fraction, meaning I read that as the sum of two 2s multiplied by eight halves, which is 16.

Impartial8 hari yang lalu

I just want to advocate for the 1 side here, as that is how I saw it. Contrary to what many in the comments like to think, not all 1-ers are idiots who couldn't pass 8th grade; I am currently taking Precalc as a freshman, having taken two online courses last year and having passed both finals. I am also aware of the order of operations, and had the problem been 8 / 2 * (2 + 2), I certainly would have solved it as 16, even though I know that 2 * (2 + 2) is equivalent to 2(2 + 2). This is a misleading fact-- however --because, while those expressions have the same value alone, it would be possible for them to act differently in a given context. For example, 2 - 1 = (2 - 1), but 3 - 2 - 1 =/= 3 - (2 - 1), in the same way that, theoretically, 2 * (2 + 2) = 2(2 + 2), but 8 / 2 * (2 + 2) would not equal 8 / 2(2 + 2) if one assumes that a(b) binds tighter than a * b, which was my assumption. I still believe that parenthetical multiplication should bind tighter than explicit multiplication, and with a bit of research, this seems to still be a disputed issue. That proves that this is not such a basic, 3rd-grade math problem, but a useless argument based solely around the ambiguity of certain mathematical syntax. Please, people, just write your division expressions in fraction notation.

This is a problem written in terrible form intentionally trying to screw with people. To get 16 as an answer there SHOULD be parenthesis around 8/2.
