<h3>How to convert to scientific notation</h3>
- 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
- Count how many places you moved the decimal point. Let say it is Y.
- If you moved the decimal to the left b is positive.
- If you moved the decimal to the right b is negative.
- If you did not need to move the decimal b = 0.
- Write your scientific notation number as X x 10^Y.
