1. Error Message Table
• General calculation errors
When you see
It means this:
this message:
Syntax • Illegal syntax
ERROR • Attempt to input an illegal command
Ma ERROR • Calculation result that exceeds the
calculation range.
• Intermediate or final calculation result
is outside the allowable calculation
range.
• Mathematical error (division by zero,
etc.)
Stack ERROR Execution of calculations that exceed
the capacity of the stack for numeric
values or stack for commands.

So you need to do this:
Press J to display the error and
make necessary corrections.
Check input values and make
corrections to ensure that values are
within allowable limits.
• Simplify the formulas to keep stacks
within 10 levels for the numeric
values and 26 levels for the
commands.
• Divide the formula into two or more
parts.
Input an integer value.
Input a matrix value.
Input a matrix or vector.
Input a list value.
Input a real number value.
Check the polar form.
Change the values so the size
relationship required by the syntax is
maintained.
