    Examples

    Rounding to 2 significant figures:

    * 12,300 becomes 12,000

    * 0.00123 becomes 0.0012

    * 0.1 becomes 0.10 (the trailing zero indicates that we are rounding to 2 significant figures).

    * 0.02084 becomes 0.021

    * 19,800 becomes 20,000

    One issue with rounding to n significant figures is that the value of n is not always clear. This occurs when the last significant figure is a zero to the left of the decimal point. For example, in the final example above, when 19,800 is rounded to 20,000

    Therefore 5306 =

    1 sig fig = 5,000

    2 " " = 5,300

    3 " " = 5,310

    More help on Wikipedia.

    Good Luck!

    Significant figures just means how many digits you keep from the left, then make up rest with zeros. The significant digits stay the same if less than 5 or are increased by 1 otherwise. 5306 becomes 5000 in one significant figure, 5300 in two significant figures, 5310 in three significant figures.

    1st: 5 x 10 to the 3

    2nd: 5.3 x 10 to the 3

    3rd: 5.30 x 10 to the third
