## Converting to Scientific Notation

**Converting to Scientific Notation**

** Step 1 :- **Position the decimal point. Place a caret, ^, to the right of the

first nonzero digit, where the decimal point will be placed.

* Step 2:- *Determine the numeral for the exponent. Count the number

of digits from the decimal point to the caret. This number gives

the absolute value of the exponent on 10.

** Step 3:- **Determine the sign for the exponent. Decide whether multiplying

by 10^{n}should make the result of Step 1 larger or smaller. The

exponent should be positive to make the result larger; it should

be negative to make the result smaller.

**Converting from Scientific Notation**

Multiplying a number by a positive power of 10 makes the number larger,

so move the decimal point to the right *n *places if *n *is positive in 10* ^{n}*.

Multiplying by a negative power of 10 makes a number smaller, so

move the decimal point to the left places if │*n│ *is negative.

If *n *is 0, leave the decimal point where it is.
