Numbers In Science

Front 1

What is Accuracy?

Back 1

How close a measurement is to the real value.

Front 2

what is precision?

Back 2

HOw close a measurement is to other measurements.

Front 3

What is Significant Digits?

Back 3

The digits in a measurement that are known with certainty plus one final digit, whic is estimated.

Front 4

What is estimation?

Back 4

An approximate measurement or calculation.

Front 5

what are the steps of significant digits

Back 5

1. Determaine where to start
2.Scan for first nonzero or zero with bar.
3All remaining digits are significant.

Front 6

what are some examples of signtific digits

Back 6

with out decimal...32100 start to the right
with the deciaml 0.0123 start to the left.
other examples are 400,100
0.1004

Front 7

What is Scientific Notation.

Back 7

is a system of numerical notation created to represent large and small numbers

Front 8

What are some examples of Scientific Notation?

Back 8

1.Write significant digits when the deciaml point after the first digit.
2. Multiply by a factor of 10
3.Determine the exponent.Count how far the deciaml point needs to move. 6.69
6.69*10
6.69*10 to the third

Front 9

what is the first step in writing in scientific notation?

Back 9

is detemaining the significant digits. Significant digits are the digits of a number beginning with the first digit on the left is not a zero and ending with the last digit on the right that is not a zero.Zeros that serve only as placeholders are not significant digits

Front 10

what are some rules that will help you when determaining these things?

Back 10

1.If the number does not have a deciaml point start from the right and scan past any zeros until you reach a nonzero digit or a zero with a bar.The remaining digits are significant.
2.If the number has a decimal point,start from the left and scan past any zeros until you reach a nonzero digit or a zero with a bar.The remaining digits are significant.
