Errors

An error will occur if an operation exceeds the calculation ranges, or if a mathematically illegal operation is attempted. When an error occurs, pressing gor yautomatically moves the cursor to the place in the equation/number where the error occurred. Edit the equation/number or press sto clear the equation. For details, see page 76.

Memory Calculations

This calculator has 11 temporary memories (A-H and X-Z), one independent memory (M) and one last answer memory (ANS). It also has various variables for use in ﬁnancial calculations and statistical calculations.
