    First of all, "bumps" don't help. Second, if you need an answer right away (you only waited 2 hours) this probably isn't the best place to go. You WILL get an answer, probably within a day. Don't be so impatient!

    As for errors, if you have to report an error of 119 to one significant digit that would be either 100 or 1 x 10^2. That means if your measured value is 54619 then you would report a value of [tex]54600 \pm 100[/tex].
