Convert to scientific notation:
12 million
Count six zeros, move the decimal an additional two to the left: 1.2 x 10^7
Convert to scientific notation:
286 thousand
Count three zeros, move the decimal an additional two to the left: 2.86 x 10^5
Convert to scientific notation:
134 millionths
0.000134 = 1.34 x 10^-4
Note that millionths requires six positions. The last digit, 4, is at the 'millionth' marker.
Explain how to convert positive numbers greater than one to scientific notation
Get the coefficient and exponent.

For the exponent, count from the current decimal position, to the position immediately after the first number.

Create the coefficient by transcribing the numbers, inserting a decimal after the first number.

23000 = 2.3 x 10^4
Explain how to convert positive decimal numbers to scientific notation.

Find the:
- Range of included numbers
- The coefficient
- The exponent
A decimal number between 0 and 1 will have a negative exponent.

For the exponent/magnitude, count right, from the current decimal to the space after the first non-zero number.

The coefficient begins with the first non-zero number, then a decimal, and then the remainder of the numbers.

Don't forget that the exponent is negative.

.0003408 = 3.408 x 10^-4
