You may exhibit your stem units using this notation,
depending on the preferred conventions of the
professor/reader.
Do not forget the title.
This illustrates what
the display is about.

Remember spaces, and
do not put commas. Also
only one digit is denoted
for each leaf; not more.
Scientific Notation:
Do not fall

or
surpass
13 stems.
Only
repeat
stems
once,
twice or
five times.
In this notation the original number is written in terms
of base 10. Where numbers smaller than (+/- 1) is
written as10-n and numbers greater than (+/- 1) is
written as 10n.
e.g.
Original # (25619) Æ Sci.Notation 2.5619 x 104
25619.0
Decimal moves from right to left
when number being denoted is
greater than one. In this case four
times. This is written to a positive
power of base 10 as shown above.
Original # (0.00025619) Æ Sci.Notation 2.5619x10-4
0.00025619
Decimal moves from left to right
when number being denoted is
less than one. In this case four
times. This is written to a negative
power of base 10 as shown
above.
Remember when writing in this format:
This must be shown in order to
represent the unit of the actual
number. If required, put a
measurement of scale as well
(e.g. ml, cm…)
•Only one number is represented before the decimal
•The number represented before, is an integer not
including 0
•The decimal places moved is the number written to
the power of 10. Negative when moved from left to
right, and positive when moved from right to left.
