Maybe it's just me....

BUT

It looks like your symbolic notation means that you need to ADD x[sub:3or96hhs]1[/sub:3or96hhs]/49 + x[sub:3or96hhs]2[/sub:3or96hhs]/49 + x[sub:3or96hhs]3[/sub:3or96hhs]/49...up to and including x[sub:3or96hhs]11[/sub:3or96hhs]/49. Remember that when you add fractions with the same denominator, you add the numerators, and put the result over the common denominator. So, for example, if you are adding 3/49 + 5/49 + 16/49, that would be (3 + 5 + 16)/ 49, or 24/49

Follow those directions, and you should be able to arrive at the correct answer...except that your directions say that you need to express your answer to two decimal places.
 
I get
add -2,82,87,-1,-51,-2,53,87,-20,32,35=300
300/49=6.12244

Round two decimals = .061244 or 61.22? I don't know which way I should go.
 
If my answer says round two decimals which way do I go with the decimals? Thanks

300/49=6.12244

Let's see if we can use a bit of common sense here.

300/49 is VERY CLOSE to 300/50, right?

300/50 is 6.

So....
your answer should be very close to 6.

Where should you put the decimal point in 61244 so that you get a result that's close to 6?

And "round to two decimal places" means that your final answer should have two decimal places in it.

EXAMPLES:.....48.909168 would be 48.91 to two decimal places
.................0.038483 would be 0.04 to two decimal places
