You may talk about the walk to school being 12 minutes, not 12.3547937... minutes. That is because 2 significant figures is all that is needed to convey the relevant information. Furthermore, you will not have the equipment to record your time to that degree of precision.
You measure your height in [metres and] centimetres or [feet and] inches, but to no more accuracy. Your mass is measured in whole kilograms - at most 3 sig figs - not as 105.697531 kg!
Although the mathematical constant, pi, has been calculated to over 10 trillion decimal digits (as of Sept 2014), many people will use only 3 sig figs (3.14) and most of the rest will stop at 6 sig figs (3.14159).
The answer depends on what operations were used. There should normally not be more significant figures in the answer than in any of the numbers used in the calculation.
4 of them.
The rules for identifying significant figures when writing or interpreting numbers are as follows: All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5). Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3. Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2. Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.
The degree of accuracy of the measuring instrument.
we will do maths daily in our life but for calculations it takes a lot of time so in shortcut Vedic maths was used. so it is important for us in daily life

There are three significant figures in 00312. Zeros used as placeholders at the beginning of a number are not considered significant.
370.0 has four significant figures. Zeros used for precision purposes, such as the zero after decimal point in this case, are considered significant.
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

significant figures in the original numbers used in the calculation. This means the final answer should be rounded to the same number of significant figures as the number with the least amount of significant figures.
The appropriate number of significant figures to use in expressing the result of 51.6 x 3.1416 is three. This is because the factors each have three significant figures, so the result should also have three significant figures. The answer would be 162.
It depends upon how you got to the 12, for example: 28.6 - 16.6 = 12.0 Because each of the numbers that was used to get to the 12 had 3 significant figures, you should write the 12 with three significant figures also. However: 29 - 17 = 12 In this case, each of the numbers that was used to get to 12 had only 2 significant figures, so use only 2 significant figures in the 12.

Just look at the house we are in,the solid figures play a key role in building the house. Look at the desk,the ball,the table,the cup,so many things in our life,they are designed by solid figures first.we can say,it is the solid figure make our life more artistical.
There are two types of significant figures, measured and exact. Numbers are often rounded to avoid reporting insignificant figures. Numbers can also be rounded merely for simplicity rather than to indicate a given precision of measurement.
