In the PEMDAS method, equation typically starts from left to right parenthesis, then Exponents, and after that division, addition and subtraction. And the second type is BODMAS method, in this solved the equation from right to left.
These kinds of conundrums are purposely meant to divide and conquer, and predictably, the seemingly simple problem posed in the offending tweet—8÷2(2 2)—practically caused a civil war in the magazines. Bobby Lea, test editor (and three-time Olympic cyclist): i ride bikes Matt Allyn, features director: for anyone that wants a longer explanation of why you divide before multiply in this case Pat Heine, video producer: ..writes out PEMDAS and then does PEDMASMatt: you clearly didn't listen Pat: i didn't...i was busy correcting her math. Matt: ok, Derek, the video's for you Pat: if you get 16 it's because you don't know the difference between brackets and parentheses.
Naturally, we took to Slack to hash out our differences. Morgan Petruny, test editor: I agree with Derek and disagree with You Tube. Bobby: This sounds like a conversation the belongs on the Not My Job segment of Katie Fogel, social media editor: polling our IG audience on this now...
As per Mashable study, Maths rules may be varied as per different location in the world.
There are several different methods to solve this type of equation like PEMDAS method, BODMAS method, etc.
This article was co-authored by Paul Chernyak, LPC.
Paul Chernyak is a Licensed Professional Counselor in Chicago.So he suggests all mathematicians and physician try to make some certain rules for such type of equations.He also added as such equation should be solved all ambiguous equation with the help of some specific rules.Part of the world use PEMDAS method, and others use BODMAS method.Its a type of ambiguous equation, one can solve this by either method and answer also varied.Here’s a heated chat between the editors who stopped doing any semblance of actual work for the day to solve an equation designed to flummox fourth graders—and make many enemies in the process—followed by insight from real mathematicians and physicists who begrudgingly responded to our request for comment to solve the enraging math debate, once and for all. What if you want to do it the long way and use the distributive property and distribute the 2 first? Or does the distributive property suddenly no longer apply? Derek: I trust Morgan because she's had a math class this decade. Dan: smart Berkley people say it's too ambiguous to say; PEMDAS isn't a mathematical convention as much as a teaching method Pat: multiplication/division::right/wrong Taylor Rojek, associate features editor: Biggest takeaway isn't that anyone sucks at doing math, but that this person sucks at writing out clear equations Bill Strickland, editorial director: MAKE IT CONTENT! Pat: The equation is not written according to ISO standards, leaving ambiguity of interpretation and the real answer is we need to teach better math writing.Pat: Wikipedia says you hate America if you get 16. Ambiguous PEMDASAmbiguous problems, order of operations, PEMDAS, BEMDAS, BEDMASaka..Taylor said, but from Harvard Morgan: aka...teach the distributive property instead of random acronyms Pat: When written according to ISO standard, the answer is 1.Bobby: i'll work on preparing my argument now Taylor: You've got, what, 11 years to perfect it Bobby: time is on my side which is code for: I can put this off for a reeeaaaalllly long time Pat: which is code for "ask your mother"Bobby: she likes to claim she's good at math. Mathematicians try to make rules as precise as possible.She may come to rue the day she bragged about that Pat: "This won't help me win millions of dollars playing Fortnite tho"According to order of operations, you solve whatever is in the parentheses first. Then, in PEMDAS, multiplication and division take equal precedence, so you’d do the first that occurs from left to right. Thus, it’s 16 according to classic order of operations. According to strict order of operations, you’d get 16, but I wouldn’t hit someone on the wrist with a ruler if they said 1.And the way it’s written and present on the internet is very ambiguous.In addition, he added as, in math, there are lots of time such an ambiguous situation happens.
