k Clearing Equation Memories
After entering an equation calculation mode (SIML or POLY), clear the calculation
memory for that mode. In the case of SIML, use the function keys to specify the
number of unknowns, from two (1) to six (5). In the case of POLY, use the func-
tion keys to specify either two (1) or three (2) polynomials.
2(DEL)
Press 1 (YES) to clear the equation memories of that mode (SIML or POLY), or
6 (NO) to abort the clear operation without clearing anything.
