Is it 1 or 16?

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.

What is the correct answer to 2 2x4?

The answer for 2+2×4 = 10. I followed PEMDAS to solve this problem. i.e. Parentheses Exponential Multiplication Division Addition Subtraction.

Is Pemdas or Bodmas correct?

BODMAS stands for Brackets, Orders, Division, Multiplication, Addition and Subtraction. BIDMAS and PEMDAS do exactly the same thing but using different words. BODMAS explains the “Order of Operations” in maths and BIDMAS AND PEMDAS do exactly the same thing but using slightly different words.

What does Bodmas stand for?

Bodmas stands for Brackets, Orders, Division/Multiplication, Addition/Subtraction.

Why Bodmas is wrong?

Wrong answer Its letters stand for Brackets, Order (meaning powers), Division, Multiplication, Addition, Subtraction. ... 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 are the 7 hardest math problems?

The problems are the Birch and Swinnerton-Dyer conjecture, Hodge conjecture, Navier–Stokes existence and smoothness, P versus NP problem, Poincaré conjecture, Riemann hypothesis, and Yang–Mills existence and mass gap.

Does Bedmas apply when there are no brackets?

Just follow the rules of BODMAS to get the correct answer. There are no brackets or orders so start with division and multiplication. 7 ÷ 7 = 1 and 7 × 7 = 49.

What does 2/3rds mean?

Two-thirds of something is an amount that is two out of three equal parts of it. American English: two-thirds /ˌtuˈθɜrdz/ Brazilian Portuguese: dois terços.

Are there any exceptions to PEMDAS?

There are two exceptions: If the expression starts with division and then multiplication, and there is no addition or subtraction sign between the multiplication and division, perform division first and multiplication second.

Does Bodmas apply if no brackets?

BODMAS Test Questions. The rules of BODMAS are easiest to understand with some practice and examples. Try these calculations yourself and then open up the box (click on the + symbol to the left) to see the workings and answers. There are no brackets or orders in this calculation.

Do you multiply first if no brackets?

Because there are no parentheses and exponents, start with the multiplication and then division, working from left to right.

Does Pemdas apply when there are no parentheses?

Without parentheses, PEMDAS rules imply that you must do division first. With parentheses, the 3x now becomes a group. Multiplication technically must occur before division (but you can still do algebraic simplifications, like cancelling a common factor).

Does order of operations apply when there are no parentheses?

If there are multiple operations at the same level on the order of operations, move from left to right. you work like this: First notice that, there are no Parentheses or Exponents, so we move to Multiplication and Division. ... Within a set of parentheses, the order of operations should be followed.

Does Bedmas apply if there are no brackets?

Just follow the rules of BODMAS to get the correct answer. There are no brackets or orders so start with division and multiplication. 7 ÷ 7 = 1 and 7 × 7 = 49.
