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.

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.

solution and try again.
