Working with Scientific Notation
|In Normal Mode:
(If a problem is already expressed IN scientific notation,
it may be possible to simply enter the problem on the home screen in
Normal mode to arrive at the answer.)
Expressed in decimal notation, 4.726 x 10-3 is
(1) 0.004726 (2) 0.04726
(3) 472.6 (4) 4,726
Note: In Normal mode, if the
answer cannot be displayed in 10 digits or the absolute value is less
than .001, the answer will appear in scientific notation.
|In Scientific Mode:
(If a problem asks for the answer to be in expressed in
scientific notation, change the Mode to
Sci (scientific mode).
The distance from the Earth to the Sun is approximately 93
million miles. A scientist
would write that
(1) 9.3 x 106
(2) 9.3 x 107
(3) 93 x 107 (4) 93 x 1010
In scientific mode (Sci),
all answers will be expressed in scientific notation.
Note: The calculator is using the notation
9.3 E 7 to mean 9.3 x 107 .
To insert the E into a calculation,
press 2nd (comma)
The face of the calculator reads EE
above the comma key, but only one E will appear on the screen for your
scientific notation. Can be used in either
Normal or Sci mode.
(Point of interest: The double EE is used in Engineering
Mode (Eng) where the
powers of 10 are multiples of 3. The form is a = b x 10n; where b is a number from 1 to less than 1000, and n is a multiple of 3.)
