Numeric Solver 663
Clearing Variables Before Leaving the Numeric Solver
When you solve an equation, its variables still exist after you leave the Numeric Solver. If
the equation contains single-character variables, their values may inadvertently affect
later symbolic calculations. Before leaving the Numeric Solver, you may want to:
1. Press:
@2ˆ
to clear all single-character variables in the current folder.
2. Press ¸ to confirm the action.
The screen returns to the solver’s
eqn: line.
Note: Any time you want to clear single-character variables listed in the solver, use:
