Sig Fig Rules
The rule that states that all zeros that come BEFORE a non zero are not significant.
What is the Leading Zeros Rule?
1155
What number has 4 sig figs?
how close a series of measurements are to one another or how far out a measurement is taken.
What is precision?
The non zero number that comes before the decimal place
What is the furthest non zero to the left in a number being converted to scientific notation?
27498
What is 2.7498 x 10 ^4 in standard notation?
The rule that states that zeros captive between two non zeros are significant
What is the sandwich rule?
0.0024
What number has 2 sig figs?
they are used to indicate the precision of a measured number or to express the precision of a calculation with measured numbers.
What are significant figures used for?
The number(s) that come after the decimal place in Scientific Notation
What is any significant figures other than the furthest left non zero?
6006
What is 6.006 x 10^3 in standard notation?
The rule that states that zeros preceding a non zero number are only significant IF there is a decimal place present.
What is the Trailing Zero rule?
What number has 2 sig figs?
Makes calculations with unusually large or small numbers less cumbersome
What is Scientific Notation?
The representation of the true number that has been moved between standard and scientific notation.
What is the power of 10 in scientific notation?
00.000089
What is 8.9 x 10 ^-5 in standard notation?
The kind of numbers that are ALWAYS significant
What are non zero integers?
9009.65
What number has 6 sig figs?
Answers are rounded to the nearest decimal place because the final result can be no more accurate than the least accurate measurement.
Why do we round addition and subtraction answers to the smallest decimal place of the numbers used?
Number of decimal places moved between scientific notation and standard notation
What is the exponent in scientific notation?
3.00
What is 3.00 x 10 ^0 in standard notation?
The rule that states that the only significant figures in scientific notation are the numbers that come before the exponential values.
7.901 x 10^3
What number has 4 sig figs?
We round to the smallest sig figs because the final result can be no more accurate than the least accurate measurement.
Why do we round multiplication and division answers to the smallest sig figs of the numbers used?
If there is only one sig fig this format is allowed.
When can there be no decimal place in scientific notaiton?
57 x 10^-2
What is 5.7 x 10 ^-1 in standard notation?
