• To change the value of a coefficient that you already stored by pressing w, move the
cursor to the coefficient you want to edit. Next, input the value you want to change to.
• Pressing 3(CLR) clears all coefficients to zero.
4. Solve the equations.

• Internal calculations are performed using a 15-digit mantissa, but results are displayed
using a 10-digit mantissa and a 2-digit exponent.
• It may take considerable time for the calculation result of a high-order equation of 3rd degree
or higher to appear on the display.
• An error occurs if the calculator is unable to find a solution.
• High-order equation calculations may not produce accurate results when the equation has
multiple solutions.
• After calculation is complete, you can press 1(REPT), change coefficient values, and then
re-calculate.
