*Since both profit and loss amount is same so, it’s broke even. The distance light travels in one year is approximately 5,870,000,000,000 miles. In order to have a yearly income of $ 500, he must invest the remainder at: (a) 6 % , (b) 6.1 %, (c) 6.2 %, (d) 6.3 %, (e) 6.4 % Income from $ 4000 at 5 % in one year = $ 4000 of 5 %. The distance light travels in 100 years is: (a) 587 × 10 5. *

Dan Roe, test editor: Right but it's multiplication/division, not multiplication then division Morgan: BUT multiplication with parentheses trumps division. Kit Fox, special projects editor: Isn’t the question and ambiguity here on when the parentheses disappear? Or do they go away once you solve the mini equation inside the parens first. I am on team 1I also have not taken a math class in over 10 years Trevor Raab, photographer: My question is to what real world scenario would this apply to Brad Ford, test editor: Math class?

Trevor: ahh the classic learn to do math to learn to do more math Bobby: school ain't real world Morgan: Generating heated and polarizing office discussion Brad: Bobby, tell that to a 6th grader.

Every few months, the Internet eats itself over some kind of viral riddle or illusion, each more infuriating than the last.

And so, like clockwork, this maddening math problem has gone viral, following in the grand tradition of such traumatic events as The Dress and Yanny/Laurel.

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.

Whether you are a mathlete or math challenged, Photomath will help you interpret problems with comprehensive math content from arithmetic to calculus to drive learning and understanding of fundamental math concepts. The text recognition is near perfect, even with my sloppy handwriting.

The solution, no matter how complicated, is accompanied with steps which go in detail to explain the problem and it's properties.
