For multiplication and division, you keep the number of significant figures (sig figs) that were in the number with the lesser number of figures. For example, 12345 divided by 555 on a calculator gives 22.243243... but you would represent this as 22.2 because 555 has only 3 sig figs. That said, sig figs are a bit silly in that 99 is much more significant than 10, though both have two digits. Going from 99 to 100 is a 1% change, but going from 10 to 11 is a 10% change. When doing calculations, you should in general NOT round intermediate answers to sig figs, but only the final answer. It's usually best if possible to do the calculation symbolically (such as X is the number instead of 12345) and solve for your final answer, and THEN do all the calculations at once on a calculator, rather than writing down lots of intermediate values (and rounding many out of laziness.) Alternatively, do the calculations in a spreadsheet where you can show all intermediate numbers but preserve them to their full significance, and be able to check your work, unlike with most calculators.
The rule for significant figures is that when adding, subtracting, dividing, or applying any mathematical treatment, one cannot calculate a result that has more significant digits than that of the input with the least number of significant digits. This is because any result cannot be more accurate than the least accurate input.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
you take the lowest significant figure in the equation and that is the sig fig of your answer
When adding or subtracting significant figures(sig figs), the answer will be significant to the same number of decimal places as the number with the least number of decimal places used in the calculation. Example: 12.44+1.6+133.887=147.927 ==>147.9
Take the least number of decimal places when adding or subtracting, therefore the answer is 17 to no decimal places.If it was 14 x 3.078 the answer would be 43 to 2 significant figures. The rule for multiplication/division is to use the least number of sig figs in the components: 14 has 2 and 3.078 has 4 so the answer should use 2.
Three. There are no leading or trailing zeroes.
I believe you determine Organic Nitrogen by subtracting Ammonia Nitrogen from Total Kjeldahl Nitrogen.

When adding and/or subtracting, your answer can only show as many decimal places as the measurement having the fewest number in the decimal places.

Three significant figures: two before the decimal point and one after.
Significant figures are used to receive a more accurate number. To obtain the number you you multiply or divide the quantities, leave as many significant figures in the answer as there are in the quantity with the least number or significant figures. If adding or subtracting quantities, leave the same number of decimal places in the answer as there are in the quantity with the least number of decimal places
Forget about "significant figures"; those are used to determine the precision when you multiply or divide. When adding numbers, the rule is that the result should be rounded according to the precision of the least accurate of the addents. In this case, to one decimal digit.
