• Internal calculations are performed using a 15-digit mantissa, but results are

displayed using a 10-digit mantissa and 2-digit exponent.

• This unit performs simultaneous linear equations by placing the coefficients

inside of a matrix. Because of this, as the coefficient matrix approaches zero,

precision in the inverse matrix is reduced and so precision in the results

produced also deteriorates. For example, the solution for a linear equation with

three unknowns would be calculated as shown below.

• An error occurs whenever the unit is unable to solve the equations.

• Pressing 1 (REPT) returns to the initial display of the Linear Equation Mode.

Depending on the coefficients that you use, it may take considerable time for

the calculation result of simultaneous linear equations to appear on the

display. Failure of a result to appear immediately does not mean that the unit

is not functioning properly.

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 Linear Equation Mode, press the 3 (CLR) function key. This

operation clears all the coefficients to zero.
