Re: 8/2(2+2) = ?
It depends.
If you are tying to show:
8 divided by 2(2+2), then the answer is 1
If you are trying to 8 divided by 2 times (2+2), then the answer is 16.
hard to tell what you are actually representing in that incorrectly draw expression.
8
-------
2(2+2)
or
8
-- * (2+2)
2
You can't really tell if you want that division to go to the rest of the equation.
Judging by the look of it, you want to do parenthesis first -> 8/2(4). Then it you can just do division or multiplication or order from left to right. 8/2 = 4 times 4 equals 16.

Ok re did my calculations, came up with 1 0000 this time. Final answer.

Re: 8/2(2+2) = ?
I was always taught multiplication and division were grouped as a whole and you should precede from left to right. Same with addition and subtraction.
Besides, you wrote the expression incorrectly.
You want it to write:
8
-----
2(2+2)
Not
8
-- * (2+2)
2
Which it literally states because the division symbol does not embrace the entire expression.

8/2x(1+1)² =8/2x(1²+2x1x1+1²)
find out the name of the formula i just used.

8/2(4) <---Parentheses still thur! Let's get rid of them!
8/8
1

PROFIT
EDIT: Spin, to get 16, the equasion can be written as.
(8/2)(2+2)
(4)(2+2)
(4)(4)
16

÷ and / are not the same.
8/2(2+2) = 1
8÷2(2+2) = 16

That still reads:Mecca wrote: 8/2(4)
8
-- * 4
2
Because the division symbol is not distributed over the 2(4).
Math is all about notation my friend.
Re: 8/2(2+2) = ?
Really!? My bad then, I was too lazy to look up the alt code for the division symbol or copy paste. / is the default symbol for division in the programming languages I have worked with so I wasn't thinking.apparition wrote:÷ and / are not the same.

There are parentheses, so get rid of those first.INW wrote:That still reads:Mecca wrote: 8/2(4)

Exactly! So 8/2 = 4(4) = 16. not 1.Mecca wrote:There are parentheses, so get rid of those first.INW wrote:That still reads:Mecca wrote: 8/2(4)

8/2*4
I just found this website to justify my answer that it is indeed 16, not 1.
http://www.purplemath.com/modules/orderops.htm
15/3*4 = 20. Not 5/4.
I know my math.
Looked that up to make sure I wasn't looking like an idiot.PurpleMath wrote:When you have a bunch of operations of the same rank, you just operate from left to right. For instance, 15 ÷ 3 × 4 is not 15 ÷ 12, but is rather 5 × 4, because, going from left to right, you get to the division first.
I am right mecca
