k k k k k Changing Coefficients

You can change a coefficient either before or after you register it by pressing w.

u u u u u To change a coefficient before registering it with w

Press the A key to clear the current value and then input another one.

u u u u u To change a coefficient after registering it with w

Use the cursor keys to highlight the cell that contains the coefficient that you want to

change. Next, input the value that you want to change to.

k k k k k Clearing All the Coefficients

While in the Quadratic or Cubic Equation Mode, press the 3 (CLR) function key.

This operation clears all the coefficients to zero.
