= significant figures = and got
For addition and subtraction, the result should have as many decimal places as the measured number with the smallest number of decimal places.
Make sure the answer is rounded to significant digits as well.
The number 1.84 x 103 has three significant figures, 1.84. The 103 part of the number does not count when determining significant figures.
There are 3 significant figures in this number.
There are 6 significant figures in this number.
4.884 has four significant figures and 2.25 has three significant figures. 4.884 x 2.25 = 10.989 = 11.0 rounded to three significant figures. When multiplying or dividing, the result must have the same number of significant figures as the number in the problem with the fewest significant figures.
12.5912
You count the number of figures from left to right starting with the first number different from 0. Example: 205 has 3 significant figures 0.0000205 has 3 significant figures 0.000020500000 has 8 significant figures

The number 1.84 x 103 has three significant figures, 1.84. The 103 part of the number does not count when determining significant figures.
addition multiplication division subtraction
If your question was 'what is 216 to one significant figure', the answer would be 2. This is because the two means two hundred. If your number was 0.216 and you had to round it to one significant figure it would also be 2, but if your number is 0.203 and you had to round it to two significant figures you would say 20 this is because you only count the zeros as significant figures after an actual number. For example; 0.31 to two significant figures would be 31 but 0.301 to two significant figures would be 30.
Three significant figures are in this number.
The number 805 has three significant figures.
The simple rule is: no more significant figures than the least accurate of the values in the computation. For multiplication and division, the result should have as many significant figures as the measured number with the smallest number of significant figures. For addition and subtraction, the result should have as many decimal places as the measured number with the smallest number of decimal places. (Rounding off can be tricky, but that would be another thread)
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
rules to follow in determining the number of sigificant * zero's are not significant at the end of the whole number which does not have a decimal point * EXAMPLE: 3400 ( 2 sf's) 2000 (2sf's)*
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
There are six significant figures in this number (i.e. all the figures here are significant).
