u Error during calculation

Press the J key to clear the error and display the coefficient. Try inputting values for the

coefficients again.

kClearing Equation Memories

1.Enter the equation calculation mode (SIML or POLY) you want to use and perform the function key operation required for that mode.

•In the case of the SIML mode (1), use the function keys to specify the number of unknowns.

•In the case of the POLY mode (2), use the function keys to specify the degree of the polynomial.

•If you pressed 3(SOLV), advance directly to step 2.

2.Press 2(DEL).

3.Press 1(Yes) to delete the applicable equation memories or 6(No) to abort the operation without deleting anything.
