Sig figs and addition and subtraction: Examine the two measured quantities that you are adding or subtracting, and note how many sig figs each has. After doing the adding or subtracting operation, round the answer to the same number of sig figs as the measurement with the least number of digits TO THE RIGHT OF THE DECIMAL.

significant figures (often abbreviated as “sig figs”) The last digit written in a measurement is the number that is considered to be uncertain. The number of sig figs in a measurement are all of the certain numbers, plus one that is uncertain (estimated) Rules for Counting Significant Figures. Nonzero integers are always significant. Zeros

We will not be as tight on sig. figs. as we are in our analytical classes, but the significant digits presented should be meaningful relative to the accuracy and precision of your measurements and abilities Make ample use of tables and figures, which should be labeled and presented in a quality manner.
