Order of operations you filthy casuals!
@spongeblade, It's PEMDAS not DoWhateverTheFvckYouWant
@SimonPetrikov, it’s BEDMAS where I grew up, the B standing for brackets
Brackets, indices, division, multiplication, addition, subtraction. There's so many ways, but I believe USA is more PEDMAS and UK is more BIDMAS as they use parentheses more than brackets in normal usage.
@SimonPetrikov, please excuse my dear aunt sally
@TheMightyImp, damn so Canada be doing its own thing too then I guess
@Duncan5769, that's a good thing. Be boring if we were all the same :)
I need to know how you could rationally get 15 or 13 as an answer.
@LetsJustGoExtinct, 13 is closest to 10 so it must be right.
@LetsJustGoExtinct, and what exactly about the world today is rational?
@LetsJustGoExtinct, like this:
2 + 2 x 4 = 15
2 + 2 x 4 = 13
@LetsJustGoExtinct, x is obviously a variable meaning “+5+” so it reads 2+2+5+4=13
@LetsJustGoExtinct, considering you've got university professors claiming 2+2=5 and that math is a white construct, anything's possible
@Kangaroo Jacked, I've actually had 2+2=5 explained before when we did axioms. It only works in another space, not in ours and if you transform the math back to our space, the answer goes back to 4. Since I don't need axioms and made up math that works only in another vector space, I don't much care for them. Professor did it to make us go WTF!? It worked. It has its purpose but only in specific scenarios and nothing in real life calls for them. If you just whip out odd math like that, you're wrong and not doing the math correctly.
Please excuse my dear Aunt Sally!
@Dangerous Dan Spivey, penguins enjoy dead mouse sluts
8. multiplication is a lie × is just a + that's fallen over.
@payton manning, it's more stable now.
How do you even get 13 14 or 15? 16 is the only wrong answer i can understand getting
I failed maths (seriously I got less than 10% right in my final exam) and even I know you multiply first.
The correct answer is Bo Derek.
But John doesn't like others getting near his ingénue on set.
I argue that the answer is both 10 and 16 and neither is more correct than the other. It entirely depends on the situation and what the expression really means
Say you have 4 crates and each crate has 2 oranges. If you add two oranges to each crate, you get the example of (2+2)×4. (2 oranges additional oranges per crate + 2 starting oranges per crate) × 4 crates.
Say you have the same 4 crates with 2 oranges each. This time, you're given 2 oranges total instead of 2 orange per crate. Here's your example of 2+(2×4). 2 additional oranges + (2 starting oranges per crate × 4 crates).
Y'all can downvote all you want, there are two answers. PEMDAS doesn't work for everything (e.g. solve for x in 3x-7=20).
@BIessthefaII, you are describing the equivalent of "The customer is always right" when clearly they aren't saying what they want but expect the worker to decipher whats going on in their head, parentheses are their for that exact reason and to not put them is to assume someone wants to eat water with a fork
@BIessthefaII, PEMDAS works for 99.99% of the math that 99.99% of people come across including everything you stated. There are only specific times when it doesn't.
@mas2de, except it doesn't. Pemdas can work well for expressions but it does not work nearly as well with equations.
@BIessthefaII, so what you're saying is that it confuses you because you can't multiply by a variable and get a number out? If you can't multiply it yet, then go onto the next step. BTW the answer to your equation is x=9. Not that hard. It's solving for a variable, not chugging through the numbers. Your example isn't a great one but solving for a variable can also utilize PEMDAS. If it were 3(x- (7/3)) = 20, what would you do first?
F#cking hate math..
I got 8
“Am I a joke to you?”
