Quick Answer: Is It 16 Or 1 Math Problem?

How do you solve Pemdas rule?

PEMDAS is an acronym for the words parenthesis, exponents, multiplication, division, addition, subtraction.

For any expression, all exponents should be simplified first, followed by multiplication and division from left to right and, finally, addition and subtraction from left to right..

What is the correct order of operations in math?

Different mnemonics are in use in different countries. In the United States, the acronym PEMDAS is common. It stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. PEMDAS is often expanded to the mnemonic “Please Excuse My Dear Aunt Sally”.

What is the hardest math problem in the world?

Today’s mathematicians would probably agree that the Riemann Hypothesis is the most significant open problem in all of math. It’s one of the seven Millennium Prize Problems, with a million dollar reward for its solution.

What are the 7 hardest math problems?

The 7 Unsolved Mathematical ProblemsPoincaré Conjecture.Birch and Swinnerton-Dyer Conjecture.Hodge Conjecture.Navier–Stokes Existence and Smoothness.P Versus NP Problem.Riemann Hypothesis.Yang-Mills Existence and Mass Gap.

What comes first in math equations?

(You might remember this as “Please excuse my dear Aunt Sally.”) This means that you should do what is possible within parentheses first, then exponents, then multiplication and division (from left to right), and then addition and subtraction (from left to right).

Why Bodmas is wrong?

BODMAS is wrong. That’s what. … It contains no brackets, powers, division, or multiplication so we’ll follow BODMAS and do the addition followed by the subtraction: This is erroneous.

What is the answer to the math virus question?

The PEMDAS version of solving it gets the answer 16. But those who use a different method called BODAS — brackets, orders, division, multiplication, addition and then subtraction — get an answer of 1. For anyone who didn’t get 16 or 1 as an answer, well, it’s probably time to brush up on your math skills.

What is viral math problem?

What is 9 – 3 ÷ 1/3 + 1 ? This seemingly simple math problem went viral in Japan after a study found that only 60% of 20-somethings were able to calculate the correct answer, down from a rate of 90% in the 1980s. Of course the key is order of operations. (As the famous mnemonic goes, Please Excuse My Dear Aunt Sally.)

Why do calculators give different answers?

But how come one calculator of the same brand said that the answer is 1? The difference has something to do with the mode or the program of the calculator. For one, not all calculators follow the order-of-operations hierarchy, which leads to a different interpretation of the equation.

Is Pemdas wrong?

Most do the multiplication before division as PEMDAS seems to be more popular and more taught in schools. BEDMAS of PE(MD)AS appears to be taught much less. The only thing we know is that the claim that one of the answer is the only right answer, is wrong.”

Can a math problem have more than one answer?

Yes, there can be two different right answers on a math problem. Math problems are not always of the kind “find all possible solutions” as in “find all numbers that multiplied by themselves make 4”. … So one right answer is : “2 is such a number”. And another is “-2 is such a number”.

Is it 16 or 1?

Some people got 16 as the answer, and some people got 1. The confusion has to do with the difference between modern and historic interpretations of the order of operations. The correct answer today is 16. An answer of 1 would have been correct 100 years ago.

Is Bodmas or Pemdas correct?

BODMAS works in order of brackets, orders, division/multiplication, and addition/subtraction. Brackets and orders are the same as parentheses and exponents in the basic sense. … in that sense bodmas and pemdas are the very same and they are both right. if you use them as intended and not lilke most dumbfucks out there.

Is there only one way to solve math problems?

As it turns out, there isn’t always one best way to solve a given problem. … “Math problems can be approached in many different ways,” says Star, an educational psychologist and former math teacher. “When a teacher insists that there is only one way, or only one best way, to solve a problem, students are missing out.
