In addition and subtraction you take the most number of sig figs.
312.45 - 3.0 = 3.0945 X 10^2
5 sig figs 2 sig figs answer needs to have 5 sig figs
In multiplication and division it is the least number.
312.45 X 3.0 = 9.4 X 10^2
5 sig figs 2 sig figs answer needs to have at MOST 2 sig figs
in decimals if there is no number before the decimal, i.e.; 0.xxxx then leading zeros do NOT count as significant. Meaning 0.000010 is only 2 significant figures. The 1 and the zero after the 1.

What is the measurement of 29.46 cm when rounded to three significant figures?
The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". The first figure to be discarded is '6' and as this is greater than 5 then the previous figure (4) is increased by 1 (to 5). 29.46 when rounded off to three significant figures is 29.5.
What is the correct powers of ten notation for the value 483.54 with three significant figures?

Round 0.004738265 to 3 significant figures?
Significant FiguresRule 1 : Zeros must be kept to show the position of the decimal point.Rule 2 : If the first figure to be discarded is 5 or more, the previous figure is increased by 1.Rule 3 : Zeros must be retained to indicate that 0 is a significant figure.0.004738265 : - Rule 1 the part of the number 0.00 must be kept.The third significant figure is therefore 0.0047?Rule 2 the first number to be discarded is 8 therefore the previous figure is increased by 1. (3 is increased to 4)The number to 3sf is 0.00474

How would you record a measurement of 16490 grams using only 2 significant figures?
The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". When 16490 is rounded off to 2 significant figures then the first figure to be discarded is 4. As this is less than 5 then the previous figure (6) is not increased by 1. 16490 to 2 significant figures is 16000.

How many significant figures are in 0.040?
Two. There are rules of Significant figure is: RULE #1 - All digits 1 through 9 are significant. RULE #2 - Zero is significant when it is between two non-zero digits. RULE #3 - A terminal zero to the right of a decimal point in a number greater than one is significant. RULE #4 - A terminal zero to the right of a decimal point in a number less than one is significant. RULE #5 - A zero used to fix a decimal point in a number less than one is not significant. by Salim Reza
