• The coefficients and solutions recalled by the above operation are stored auto-

matically in Matrix Answer Memory (MatAns).

• When the solutions for a linear equation with 2 through 6 unknowns contain com-

plex numbers, only the real number parts are stored in Matrix Answer Memory
(MatAns).

• Coefficient and solution memory data for a linear equation with 2 though 6 un-

knowns cannot be recalled at the same time.

• The following conditions cause an error (Mem ERROR) to be generated.

When there are no coefficients input for the equation

When there are no solutions obtained for the equation
