MEMORY and STORAGE FUNCTIONS
Your calculator has two types of Memory:
1) basic Memory or Semi-Permanent, Cumulative
µ
;
2) non-cumulative Storage Registers (M1-M3).
µ
Semi-Permanent Memory
— Adds any displayed
number, dimensioned or unitless, to the semi-per-
manent, accumulating Memory. Values can be sub-
tracted from this Memory using
Ç µ
.
® ®
will recall and clear the Memory.
Ç ®
will swap
the value stored in accumulative Memory with the
value that is currently displayed.
