Nope you since you multiply 1st only the 3 is effected by the zero product property

Funniest thread ever! I actually teach math and this is a 5th/6th grade problem. You learn the order of operations way before algebra. However I have algebra students that will still screw this up.

There isn't anything wrong with how the question is written either, if they put parenthesis in the problem more people would get it right, but that is a true testament of how many people don't know how to apply the order of operations.

The problem is people use things like Please Excuse My dear Aunt Sally to teach the order of operations, that why we have people who think you have to add before you subtract and multiply before you divide.

I teach the order of operations differently 1) grouping 2) exponents 3) division/multiplication left to right 4)subtraction/addition left to right

And you can use a calculator to solve this problem. Most scientific calculators know the order of operations and will solve the problem in the correct order. Especially calculators that allow you to enter the entire problem in one step (ie: graphng calculators or Texas Instruments TI 30x and above) Now if you have one of those cheap calculator without any memory that only allows you to enter one step at a time, you will probably get the wrong answer.


Although you should keep the M/D and A/S in the same order instead of totally switching them around to confuse more dumbasses like the ones in here.

that is false addition and subtraction are equal operators(same hierarchy) , you do whichever comes first as you read the problem from left to right.
False. With addition and subtraction, the order doesn't matter. You'll still get the same answer.

7 - 4 + (3 x 0) + 1 =
7 - (4 + 0) + 1 =
7-(4+1) =<-- Mistake was putting the +1 within the parenthesis.
7-5 = 2




EDIT:
7 - 4 + 3 x 0 + 1 =
7 - 4 + 1 =
3 + 1 = 4

7 - 4 + 3 x 0 + 1 =
7 - 4 + 1 =
7 - 3 = 4

I got 4, then thinking "why would so many people get this easy a.ss problem wrong" I started to question myself and got 1. Then I see n*ggas saying it's 4 and feel stupid for being tricked into being wrong.

SMH @ these n*ggas trying to argue the wrong fu*king answer.

It's 4. If you got something other than 4, instead of arguing, go fu*king look it up, so you don't expose your dumb a.ss to the rest of Boxden.

284 posts on a simple order of operations problem. This is 5th grade sh*t. I can only imagine what would happen if these n*ggas had to do some algebra.

/end rant.

I know the answer of course
Now here's one that's written like sh*t, because when you're doing this kind of math, you wouldn't use the % sign if you're not going to use the x sign which is implied by the connection to the (). Most mathematicians wouldn't use % at all anyway lol

6 % 2 (1+2) = 6 % 2 x (1+2).
This answer becomes 3 x 3 = 9

Most math that includes division would be written with a bar for division and you don't know whether the (1+2) would be written NEXT TO 6/2 or whether 6 is over top of both 2(1+2). If you interpret 6 as the numerator, then 2(1+2) as the denominator, you would get: 6/2(1+2) = 6/2(3) = 6/6 = 1.

That is wrong though. The (1+2) is a single term due to the parenthesis, not 2(1+2).. You can imagine this as 6/2 x n, where n=3
6/2 x 3 = 9.

So, the true answer to this question is 9, even though it is somewhat ambiguous.

dont forget u do all adding before any subtraction
i only put the parenthesis (not sure if i spelled that right) around what step im on not that they are actually there in the problem but u do in this u go p.e.m.d.a.s and aint no p.e. skip to m do the lil multi then go to addition from left to right in this problem it doesnt matter but others it might but then u do subtraction last .... the only correct answer is 2 I think lol

Stay in school/college

I got 4
3 x 0 first = 0
Then you get 7 - 4 + 0 + 1 = ?

7 - 4 = 3
3 + 0 = 3
3 + 1 = 4
? = 4

You DON'T do all of the adding before any subtraction. They are considered equal operations. so addition doesn't happen before subtraction. The answer is 4

My first answer was 1. But my gf is really smart and showed me the PEMDAS and helped me after my dumbass got it wrong I got 4.

Multiplication and division first, then add or subtract.. unless there is pararethesis, then thats first. Its 4

It's MATH retard. There's no such thing as "to me." It's called the UNIVERSAL language because it's not subjective

I commend you for at least trying this problem because most dudes straight ignored it. But you're wrong.

2(x + y) = 2x + 2y

The operation looks like:

6 % 2(1+2) = ?

6 % [2(1) + 2(2)] =

6 % (2+4) =

6 / 6 =

1

It's improperly written would have been my answer. You can interpret it all sorts of ways.
