Twitter user @pjmdoll shared a math problem: 8 ÷ 2(2 + 2) = ? 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.
The answer is 16
According to the order of operations, division and multiplication have the same precedence, so the correct order is to evaluate from left to right. First take 8 and divide it by 2, and then multiply by 4. This gets to the correct answer of 16.
Which is correct: BODMAS or PEMDAS? Both BODMAS and PEMDAS are correct and used in different areas of the world. BODMAS is common in the UK while PEMDAS is used in the US. BODMAS stands for Brackets, Order, Division, Multiplication, Addition, Subtraction.
Experts say that depending on where in the world you learned math determines how you can solve the problem, there is the PEMDAS method and the BODMAS method. With that in mind, the answer is 1. The answer also is 16.
There is no universally accepted rule as there are several: PEMDAS, BEDMAS, PE(MD)AS. It is not possible to say what is correct and what is incorrect. There are different rules, leading to different results.
BODMAS is an acronym and it stands for Bracket, Order, Division, Multiplication, Addition, and Subtraction. In certain regions, PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction) is used, which is the synonym of BODMAS.
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.
It is a geometric sequence.
Now, the multiples of 2 are: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, …
Canada and New Zealand use BEDMAS, standing for Brackets, Exponents, Division/Multiplication, Addition/Subtraction. Most common in the UK, Pakistan, India, Bangladesh and Australia and some other English-speaking countries is BODMAS meaning Brackets, Order, Division/Multiplication, Addition/Subtraction.
PEMDAS term is used mainly in the US but in India and the UK, we call it as BODMAS. But there is no difference between them. The order of operations for brackets, orders, addition, subtraction, multiplication and division is the same for both the rule.
Rhyme Mnemonic: PEMDAS is a mnemonic device that helps us remember the order of operations when doing mathematics. Please, Excuse, My, Dear, Aunt, Sally= Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
As the number 16 is a composite number, it has more than one factor. The factors of 16 are 1, 2, 4, 8 and 16.
The multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80… and so on.
Eight times two equals 16.
Natural Numbers The numbers that we use when we are counting or ordering {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 …} Whole Numbers The numbers that include natural numbers and zero. Not a fraction or decimal. {0, 2, 3, 4, 5 6, 7, 8, 9, 10, 11 …} Integer.
1, 2, 4, 8, 16, 32, 64, 128, 256, ... This sequence has a factor of 2 between each number. Each term (except the first term) is found by multiplying the previous term by 2.
In mathematics, 1 + 2 + 4 + 8 + ⋯ is the infinite series whose terms are the successive powers of two. As a geometric series, it is characterized by its first term, 1, and its common ratio, 2. As a series of real numbers it diverges to infinity, so the sum of this series is infinity.
The operations included in the PEMDAS rule are performed left to right. Additionally, the PEMDAS rule for recalling the math order of operations has a few important sub-rules that must also be followed if you want to use PEMDAS correctly (and get the correct answers to math problems).
Applying the Order of Operations (PEMDAS)
The order of operations says that operations must be done in the following order: parentheses, exponents, multiplication, division, addition, and subtraction.
Expert-Verified Answer
The answer is 3 because during solving questions like that you have to use the property BODMAS that stand for Board Of Division Multiolicatiom Addition & subtraction . this is a series that how you have to solve problems when more than 2 sign come together .
The meaning is the same. Bidmas is the term more commonly used in primary schools today. Bidmas stands for Brackets, Indices, Division/Multiplication, Addition/Subtraction.
4(10+15÷5×4-2×2)
Hence, the final answer is 72. Therefore, 4(10+15÷5×4-2×2) = 72.
