Key Operations
Some of the keys of your calculator have multiple functions assigned to them. This manual uses the conventions
below to indicate the key operations required to access each function.

fx-CG100
j 2 r / 3 sj ( G ) 8 r / Pj
(1)
(1) Press j to enter " ".
This is the operation for using the function printed on the key top.
(2) After pressing sj, press the above key to enter "G", which is shown in parentheses.
This operation is used to access the function printed in green (fx-CG100) / blue (fx-1AU GRAPH) above
and to the left of the key.
(3) After pressing Pj, press the above key to enter the "C", which is shown in parentheses.
This operation is used to access the function printed in orange (fx-CG100) / red (fx-1AU GRAPH) above
and to the right of the key.
O Key and E Key
The O key and E key perform the same operation. In this manual, O is used for selecting or applying a
setting, while E is used for executing a calculation. Note, however, that it makes no difference whether you
press O or E for operations where either O or E is shown.
d/u/l/r Keys
Use these keys to move the cursor or highlighting. These keys are referred to as "cursor keys" throughout this
manual.
General Precautions for All Applications
• Calculations may take time.
A rotating icon is shown in the upper right corner of the screen while an internal calculation is in progress.
To interrupt a calculation without waiting for it to complete, press a.
Examples of time-consuming calculations
- Integral calculations (depending on f x and the range of x )
- Calculations involving matrices or vectors with a large number of elements
- Solving simultaneous equations with three or more variables or higher linear equations, or cubic or higher
order equations
- Drawing regression graphs when there is a large amount of data (especially sinusoidal regression and
logistic regression)
• Calculation results may be subject to error.
For information about your calculator's calculation accuracy and error, see
Digits, and Precision" (page
• If an error message appears, check its contents.
For the meaning of each error message, see
• Most functions are called from the Catalog menu.
