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.
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 Bodmas rule in maths?
BODMAS rule is an acronym used to
remember the order of operations to be followed while solving expressions in mathematics
. It stands for B – Brackets, O – Order of powers or roots, D – Division, M – Multiplication A – Addition, and S – 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 is 2/3 of a whole?
To find 2/3 of a whole number we have to multiply the number by 2 and divide it by 3. To find two-thirds of 18, multiply 2/3 x 18/1 to get
36/3
. 36/3 is again simplified as 12.
Does multiplication always come first?
Order of operations tells
you to perform multiplication and division first
, working from left to right, before doing addition and subtraction. Next, add and subtract from left to right. …
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.

How is Bodmas calculated?
The BODMAS rule states we should calculate the
Brackets first (2 + 4 = 6)
, then the Orders (5
2
= 25), then any Division or Multiplication (3 x 6 (the answer to the brackets) = 18), and finally any Addition or Subtraction (18 + 25 = 43).
Do calculators use Bodmas?
BODMAS or
BIDMAS must also be used when using a calculator
. Scientific calculators automatically apply the operations in the correct order, however extra brackets may be required.
