



to return to the calculation screen. The cursor will be positioned

at the location where the error occurred, ready for input.

To clear the error message:

While an error message is displayed, press

to return to the calculation screen. Note that this also clears the

calculation that contained the error.

Error Messages

Math ERROR

• 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).

→

Check the input values, reduce the number of digits, and try again.

→

When using independent memory or a variable as the argument of a
function, make sure that the memory or variable value is within the
allowable range for the function.

Stack ERROR

• The calculation you are performing has caused the capacity of the

numeric stack or the command stack to be exceeded.

• The calculation you are performing has caused the capacity of the matrix

or vector stack to be exceeded.

→

Simplify the calculation expression so it does not exceed the capacity
of the stack.

→

Try splitting the calculation into two or more parts.

Syntax ERROR

• There is a problem with the format of the calculation you are performing.

Argument ERROR

• There is a problem with the argument of the calculation you are

performing.

Dimension ERROR (Matrix and Vector Modes only)

• The matrix or vector you are trying to use in a calculation was input

without specifying its dimension.

• You are trying to perform a calculation with matrices or vectors whose

dimensions do not allow that type of calculation.

→

Specify the dimension of the matrix or vector and then perform the
calculation again.

→

Check the dimensions speciﬁed for the matrices or vectors to see if
they are compatible with the calculation.

Variable ERROR

(SOLVE feature only)

• An attempt to execute SOLVE for an expression input without any

variable included.

→

Input an expression that includes a variable.

Cannot Solve (SOLVE feature only)

• The calculator could not obtain a solution.

→

Check for errors in the equation that you input.

→

Input a value for the solution variable that is close to the expected
solution and try again.

Range ERROR
