It's PEMDAS, or as we call it in Britain, BODMAS. When faced with big sums like this, you first deal with:
Brackets (Parenthesis) - if there any sums in brackets, do them first, then
Orders (Exponents) - ie. square roots, powers etc, then
Division and Multiplication, then finally
Addition and Subtraction.
So here, there are no brackets or orders so you skip straight to the multiplication, which is at the end. Only brackets can group things together. So, if the sum was
(2+2+2-2 etc.) x 0, the answer would be 0 - but there are no brackets here, so it's sequential, ie. each number adds/subtracts/multiplies ONLY the number next to it. So, as we deal with multiplication first, you go to the end and it's 0 x 2 (because the 2 is next to the 0), then you do the additions and subtractions. So:
2+2+2+2+2+2+2+2+2+2+2+2+2+2-2+2 x 0
First you multiply the 2 x 0 to get 0, so that gets cancelled out:
2+2+2+2+2+2+2+2+2+2+2+2+2+2-2+2 x 0
Then, you can see at the end that there's a '+2-2', (ie. 2-2) which again gives 0. Cancel that out too:
2+2+2+2+2+2+2+2+2+2+2+2+2 +2-2+2 x 0
Finally, simply add up all the twos. There are 13 2s, so it's 26!
one of my good friends is in Uni in hamilton, i live in a small town about 2 hours north of Toronto, called Gravenhurst a.k.a g-hole a.k.a a **** hole.... lol
Quit thinking people are retarded for thinking it's zero; I did at first.
People assume that you multiply all the twos together, then multiply it by zero.
Whether or not there are parentheses, it's first instinct for most people when they see a "x0"
so quit whining and get over it; it's just a stupid Facebook question.
This guy speaks the truth. It's like we are conditioned (or just so lazy) to see a zero and multiplication and just go, "Ope zero." I did it too at first until I thought about it a second.
What I don't understand is that everybody is saying to multiply two by zero first.
But yet we're supposed to work it from left to right, soooooo...idk.
worst part is I think whoever made the poll was intending 0 to be the right answer, but didn't realize where he went wrong.
should have gone (2+2+2+2+2+2+2+2+2+2+2+2+2+2+2-2) * 0
Actually I think it would be like this because you can't separate two coefficients
2+2+2+2+2+2+2+2+2+2+2+2+2+2+2 - (2 * 0)
So technically the answer would be 30 - 0 simplified which is 30
Then again, I wasn't the best at math, so I may be wrong...
You should look at how I set that up again, the minus is there but because of the multiplication the negated 2 could not be separated from the 0. Therefore the fifteen twos are added to make 30 MINUS the 2*0, which is zero, to get a final answer of 30.
For it to be 26 this is how the set up should be:
2+2+2+2+2+2+2+2+2+2+2+2+2 - (2 * 0)
Note that there are only thirteen twos now.
one of my friends who is sorta smarter than me answered zero, i answered 26. i confronted her to tell her she was wrong. she got angry and said it was zero.
2+2 =4
+2+2 = 8
+2+2 = 12
+2+2 = 16
+2+2 = 20
+2+2 = 24 +2 = 28
-2 = 24
+2= 28
x 0 = ZERO. Anything times ZERO = ZERO. Doesn't matter what the other ******* numbers are. if the last thing says "x0" That means it's ZERO. Dumb asses.
**adriangunter rolled a random image** If you use order of operations like your supposed to you start with multiplying 2 by 0 to get zero then you add the rest of the 2s and subtract 2 to get 28.
or something like that
