• Move the decimal point until it is to the right of the first
nonzero digit. The result is a real number a.
• Note the number of places n and the direction that you moved
the decimal point.
Step 2
• If the decimal point is moved left, write the number as
• a x 10n.
Step 3: • If the decimal point is moved right, write the number as
• a x 10-n
