numbers expressed in scientific notation.
CCRS: 8
Step 1
• 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
Step 4
• Remove the unnecessary zeros

Step 1:
•In a x 10n, note whether n > 0
or n < 0.
• If n > 0, move the decimal n places right.
Step 2: • If n < 0, move the decimal n places left.
• Insert zeros, decimal point, and
commas as needed for place value
