No, you would only multiply the last 1 by zero, as you do multiplication first, by PEMDAS. Then, you would add  or subtract the remainder of the ones.

To answer the question, you would use PEMDAS to answer any math question, especially if there are no parentheses. 

Here is the original:
1+1+1+1+1+1+1+1+1+1-1+1+1+1+1+1*0

Here, I add my own parentheses, according to PEMDAS:

(1+1+1+1+1+1+1+1+1+1)-1+ (1+ 1+1+1) +1*0

The last phrase = 0, and we evaluate it first, because it's multiplication, so:

(1+1+1+1+1+1+1+1+1+1)-1+ (1+ 1+1+1) + 0

The first phrase =  10, because we're just adding 10 ones together, so:

(10) - 1 + (1+ 1+1+1)

Now, adding the last phrase, since I put it in parentheses:

(10) - 1 + (4)

Now, combine the first two terms:

9 + 4

And then add:

13

I posted an answer, and I bet others have, as well, but mine keeps disappearing and reappearing. O.O 

When I go to My Questions and Answers, this problem shows up, but not always does my answer. 

How would I report this problem?

You must develop a hypothesis, but then, reverse it, also known as the "null hypothesis." 

Ex.
H0: If I change the batteries in my flashlight, it will work.
Ha: If I change the batteries in my flashlight, it won't work.

Or, since the remainder of the question deals with probability:

H0: If I roll this die, it will land on one.
Ha: If I roll this die, it will not land on one.

So, you'll want to calculate your confidence interval and determine whether or not to include the null hypothesis data (how many times 3 did not come up) in the results. If you reject the null hypothesis results, the test is two-sided, or two-tailed (regarding the shape of the bell curve). http://www.itl.nist.gov/div898/handbook/prc/section2/prc221.htm

Opposite sides are congruent, opposite angles are congruent, and the consecutive angles are supplementary.

Read if you need more detail:

If this is a true parallelogram, both sets of opposite sides and angles must be equal. If one set is not equal, the lines will not be parallel. If you extend the lines through the sides, you can see the similarity between the points of intersection, in terms of the angles. Use straws, sticks, or strings to experiment with the lengths of the sides, to give you something real to prove it to yourself.

Edit:

I misread the question. I apologize.

Bill is right. If you draw lines through the parallelogram, from one corner to its opposite, then, connecting the other two opposite corners, you will create four triangles, as you do when playing with drawings of squares.

Similar to when you are able to cut a pie perfectly, you will end up with "slices" that are equal. However, in a parallelogram, two of your slices will be equal to each other, and the other two will be equal to each other, unless all four sides are equal in length, as in a square or rhombus where all of the "slices" will be the same.

Also, as Bill pointed out, the diagonal lines will be cut exactly in half by each other. 

I like to draw these out on graph paper with a ruler, as well. Then, you can measure your lines, and see that your diagonals bisect each other.
