The accuracy of the measurement device determines the number of significant figures that should be retained in recording measurements.
This depends on the mass, volume and the nature of materials.
by significance arithmetic
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Non-zero digits are always significant, so the number 12 has two significant figures.
3 significant figures. (The zero after the 5 doesn't count.) 4 significant figures if the zero after the 5 does count. A good way of expressing three thousand four hundred fifty with three, four, or five significant figures is with scientific notation: 3.45 * 103 3.450 * 103 3.4500 * 103
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
You cannot round off a number to 3 significant figures when it already has more than 3 significant figures. The number 10074 has 5 significant figures (1, 0, 0, 7 and 4). If the number were really 1.0074, then it could be rounded off to 3 significant figures: 1.01.
