1.5 =1.5 × 10^0

0.015 = 1.5 × 10^-2

0.15 = 1.5 × 10^-1

150 = 1.5 × 10^2

How to convert to scientific notation

1. Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. Let says it is X
2. Count how many places you moved the decimal point. Let say it is Y.
3. If you moved the decimal to the left b is positive.
4. If you moved the decimal to the right b is negative.
5. If you did not need to move the decimal b = 0.
6. Write your scientific notation number as X x 10^Y.
