Question of the Day: Would you cancel a streaming subscription if it started showing paid ads?
48÷2 (9+3) argument
- Thread starter Helghast
- Start date
No
any number next to a bracket is applied with the bracket
2(12) gets worked out first
actually the entire thing is one term, terms are only separated by + and -
hence voorkeur van bewerking (BODMAS?)
1. Brackets/ Hakkies
2. exponentials and roots/ magsverheffing en worteltrekking
3.deel/ divide
4. maal/multiply
5.add and subtract...
etc! see that divide is before multiply,
here is some clarification on the ambiguity that can occur via the notation,

sorry what?
6÷2 are two terms
x/y are two terms
ai boetie waar het jy wiskunde geleer?
The terms that you refer to are the numerator and denominator, its not the same thing..
Die noemer en die deeler! a fraction of variables is STILL one term!!!
because
x/y = x*y^(-1) if y^-1 = z then
x/y = x*z = xz = one term!!!!!!!!!!!!
In elementary mathematics, a term is either a single number or variable, or the product of several numbers or variables separated from another term by a + or - sign in an overall expression.

we may have been talking at cross purposes.
but your statement helps my point.
in what we are provided, we need to know what is the numerator and what is the denominator. hence why in an earlier post i linked to riddlenut.
as written i would read this from left to right (and not add any further brackets)
48 (numerator) divided by a denominator which happens to be 2(9+3)
2(9+3) is one number.
You may want to add a bracket around 48/2. But there is no bracket there. You are changing what is in front of you. there is no bracket.
EDIT: As the equation is written, 2(9+3) is the only part with brackets. If you think 288 you have been merked by how you treat this.

The answer is
2
can we close this now?
2

it depends on the notation, if you use '/' sign then yes I agree the answer is 2 hence it will only make sense if you compare it with the written notation.
if you use the divide sign then the answer is 228
48÷2 (9+3) = 228, 48÷2 (9+3) is one term,
because the entire thing is a term you cannot treat 48 and 2(9+30) as separate terms which is what you are trying to do. The BIDMAS is also applicable within the terms, and division comes before multiplication.

2 however that is not equal to
48÷2 (9+3)
=48÷2 (12)
=24 (12)
228
why are you adding brackets to (2(9+3))?
division comes before multiplication hence
48(9+3)÷2
= 48(6)
=228
would you agree?
surely xyz = zxy ?

when in fact 2(9+3) seems the more likely term that reuires brackets?
i hwas always taught that when a number is next to a bracket without a mathematical sign, that number is applied with the the bracket. where you taught different?
yup, taught to use division first. and that the bracket just means multiplication.
in any maths.
where a number stands outside a bracket without a sign. that number is applied to the bracket. ask your maths teacher.
they ****ed you up
