What are the six rules for converting to scientific notation?

Answer 1

Scientific notation is a way of representing numbers, usually very large or very small, in the form a*10^b where 1 ≤ |a| < 10 is a decimal number and b is an integer (negative or positive). a is called the mantissa and b is called the exponent. To convert a number to scientific notation:

1. If the number has no decimal point, then add one at the end.
   
2. Then move the decimal point to just after the first non-zero digit while counting the number of places you have moved it.
   
3. The mantissa of the new number, formed after moving the decimal point is a.
   
4. If the original number is negative, then so is a.
   
5. The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative.
   
6. There is no sixth rule.
