Then I saw the explanation as to how it could be 1: makes sense
6 ÷ 2 (1+2) BODMAS means brackets first
6 ÷ 2 (3)
According to BODMAS divide and multiply are equal weighting
therefore left to right rule applies
6 ÷ 2 x 3 = 9
parenthesis for multiplication are more often seen in algebra
2(4+x)=18 and such
as a result i would tend to take "2(1+2)" from the question as an element on its own that should be treated independently. i would agree with what you said if the whole thing was written
6 ÷ 2 * (1+2) = ??
turns out this isn't that much of a question. but there you go.
is assumed to be a multiply is it not?
but you're still dividing before you've completed doing the brackets
therefore sum is 6 ÷ 2 * 3
2(3) is 2 * 3
The brackets don't contain a sum and therefore as defined by BODMAS that part is comnpleted. Therefore brackets removed
Sum becomes 6 ÷ 2 * 3
when the bracket part of the sum is completed, the * returns
then we have to do it differently
the answer is 1
probably makes more sense if it's written as 6/2(1+2)
To sum up: maths is stupid.
This is like the mummies on a ship all over again.
glad i read the article.
According to "BODMAS" quoted above and the links I posted above
he quoted bodmas and then didn't complete the brackets first
6 ÷ 2 (1+2)
6 ÷ 2 (3)
now we must still do the brackets first
6 ÷ 6 = 1
did the bracket first
once done, the sum becomes
6 ÷ 2 * 3
Put the sum in here if you don't trust me
Doing the sum within the brackets first removes the brackets
Sam is twice as old as Beatrix was when Sam was Beatrix's current age.
How old are they? Full credit will be given for answers that demonstrate working.
21 and 28?
s= sam current age
b= beatrix current age
sam was aged "b" "s-b" years ago
smee, meths and cat_race are having a nice day in a park.
smee has two more apples than cat_race
meths has one less apple than cat_race
cat_race has two bananas, three apples
parenthesis are our freinds, you can never have too many. Use them as often as you can. Forget about relying on people remembering acronym rules
6 ÷ 2 (1+2) = ?
(6 ÷ 2) (1+2) = 9
6 ÷ (2(1+2)) = 1
there.....no doubt at all
lets all just try to make life easier by remembering
"Brackets are our freinds, you can never have too many"
Up the bracket
an algebra equation with too few brackets
i prefer Please Excuse My Dear Aunt Sally
have completely missed the point of the article.
for the order in which you solve an equation is a fairly recent concept, and as such is still open to interpretation. As such, we should all do as creaky says and add brackets wherever possible.
I was being a little facetious. The question is poorly written meaning that both answers are correct and down to how you interpret the form
People who haven't learned maths yet can't do sums. Is that it?
you need more brackets into your life (I can give them (to you))
