Errors
The calculator will display an error message whenever an error occurs for any reason during a calculation.
Displaying the Location of an Error
While an error message is displayed, pressing 
, 
, or 
returns to the screen that was displayed immediately before the error message appeared. The cursor will be positioned at the location where the error occurred, ready for input. Make the necessary corrections to the calculation and execute it again.
Example: When you input 14 ÷ 0 × 2 by mistake instead of 14 ÷ 10 × 2.
- 14

Error Messages
Syntax ERROR
Cause:
There is a problem with the format of the calculation you are performing.
Action:
Make necessary corrections.
Math ERROR
Cause:
The intermediate or final result of the calculation you are performing exceeds the allowable calculation range.
Your input exceeds the allowable input range (particularly when using functions).
The calculation you are performing contains an illegal mathematical operation (such as division by zero).
Action:
Check the input values, reduce the number of digits, and try again.
When using a variable as the argument of a function, make sure that the variable value is within the allowable range for the function.
Stack ERROR
Cause:
The calculation you are performing has caused the capacity of the numeric stack or the command stack to be exceeded.
Action:
Simplify the calculation expression so it does not exceed the capacity of the stack.
Try splitting the calculation into two or more parts.
Argument ERROR
Cause:
There is a problem with the argument of the calculation you are performing.
Action:
Make necessary corrections.
Range ERROR
Cause (Table app):
An attempt to generate a number table in the Table app whose conditions cause it to exceed the maximum number of allowable rows.
Action:
Narrow the table calculation range by changing the Start, End, and Step values, and try again.
Cause (Math Box app):
The value input as the Attempts (number of trials) for Dice Roll or Coin Toss is outside the allowable range or is a non-integer value.
The value input on the expression registration screen of Number Line is outside the allowable range, or you entered an inequality with an invalid maximum-minimum relationship (like 10 < x ≤ 5).
A value input on the View-Window screen of Number Line is outside the allowable range.
Action:
For Attempts, input an integer value that is within the allowable range.
On the expression registration screen, input a value that is within the allowable range. In the case of an invalid maximum-minimum relationship for an entered inequality, edit the inequality to correct the maximum-minimum relationship.
On the View-Window screen, input values that are within the allowable range.
Circular ERROR (f(x) and g(x) feature only)
Cause:
Circular reference is occurring in a registered composite function ("Registering a Composite Function").
Action:
Do not have g(x) input into f(x), and f(x) input into g(x) at the same time.
Not Defined (f(x) and g(x) feature only)
Cause:
You attempted to calculate f(x) or g(x) with f(x)/g(x) undefined.
Action:
Define f(x) or g(x) before calculating f(x)/g(x).
