this is gonna sound REALLY stupid, but....

what is the answer to this...

4-8+3

do you just go left to right and do 4-8=-4 then add 3 (my phone says yes)

or, according to BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction) do you add 8 and 3 as if they were brackets, then subtract from 4?

wow, maybe i shouldnt be taking a-level lol.

(note: im not as stupid as i sound in this post)

-1
-1 it's easy
straight from wiki:

---

In the UK, Australia and New Zealand, the acronym BODMAS is commonly used for Brackets, Orders, Division, Multiplication, Addition, Subtraction. Since multiplication and division are of the same rank, this is sometimes written as BOMDAS, BIDMAS or BIMDAS where I stands for Indices.

so you add before you subtract, right?

dude

its basic math

solve it from left to right, just as you always would...

EDIT: remember, addition and subtraction are in the same step...

no...its -1. just live with it. addition and subtraction are done at the same time
if you dont want to go from left to right, you have to add -8 and 3....
so -8+3=-5
And 4-5=-1
:P
wiki says no.

addition comes before subtraction in the acronym

AHA!!!!

yea, you do add the 8 and 3 first, but its MINUS 8

lol, missed that one, prollem solved

Your acronym is correct but I'll modify it do help: BO(DM)(AS). The division/multiplication and addition/subtraction are the same "level" and are evaluated from left to right. Think of them as piece in the hierarchy and they are always evaluated from left to right.

I'll have a bourbon.
In this problem you go left to right. Another acronym used in the US is PEMDAS, please excuse my dear aunt sally. It stands for: Parenthesis, exponents, multiplication, division, addition, subtraction.
In this problem you can just work left to right and it doesn't matter, so as you said,
4-8+3; 4-8= -4
so we can then do -4+3=-1

Or, just go left to right and get the same answer. It won't matter.
<Han> I love Hitler
in the US it's

Parenthesis
Exponents
Multiplication/Division.

or PEMDAS.

so it's -1.
M/D are in the same step, which meants from left to right. same with a/s

In Canada, we use BEDMAS E is exponents.
Using it either way, the answer is -1.
You subtract, then add, then divide, then multiply.

4 - 8 + 3 = 4 + (-8) + 3
(4 - 8) + 3 = (4 + (-8)) + 3 = 4 + (-8) + 3
4 - (8 + 3) = 4 + -(1)(8 + 3) = 4 + (-8) + (-3)

4-8+3 = (4-8)+3 and not 4-(8+3)

how has this gone for so many pages already. after 2 posts it should have been closed. a ****in monkey could do this...
for the last time i was right in theory

technically you do have to go 4+(-8+3)

i just didnt associate the minus with the 8

That doesn't make sense mathematically unless you first demonstrate that the set of integers and the operation of addition form an abelian group.

Even still, you just look at the 8 numeral as -8. Thus, -8 + 3 = -5. 4 + -5 = -1
im aware of that now
