Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work?
Wecan think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).
Here are some examples of scientific notation.
|10000 = 1 x 104|24327 = 2.4327 x 104 |
|1000 = 1 x 103 |7354 = 7.354 x 103 |
|100 = 1 x102 |482 = 4.82 x 102 |
|10 = 1 x 101 |89 = 8.9 x 101 (not usually done)|
|1 = 100 | |
|1/10 = 0.1 = 1 x 10-1 |0.32 = 3.2 x 10-1(not usually done) |
|1/100 = 0.01 = 1 x 10-2 |0.053 = 5.3 x 10-2 |
|1/1000 = 0.001 = 1 x 10-3|0.0078 = 7.8 x 10-3 |
|1/10000 = 0.0001 = 1 x 10-4 |0.00044 = 4.4 x 10-4 |

As youcan see, the exponent of 10 is the number of places the decimal point must be shifted to give the number in long form. A positive exponent shows that the decimal point is shifted that number ofplaces to the right. A negative exponent shows that the decimal point is shifted that number of places to the left.
In scientific notation, the digit term indicates the number of significant figures inthe number. The exponential term only places the decimal point. As an example,
46600000 = 4.66 x 107
This number only has 3 significant figures. The zeros are not significant; they are only holding...
