Graphing calculator.

memories can be added in this way, giving you a maximum of 59 memories
(26 + 33).
Note: To restore the default memory configuration—26 memories—specify
Defm 0.
Expanded memories are named A [ 1 ] , A [ 2 ] etc and can be used in the
same way as standard memory variables. See Example 7.
Note: When using array variables, be careful to avoid overlap of memories.
The relation between memories is as follows:

## Order of Operations

Each calculation is performed in the following order of precedence:
1.
Functions inside parentheses, coordinate transformations, and Type B
functions, that is, those where you must press the function key before
entering the argument, for example, sin, cos, tan, sin

2.
Type A functions, that is, those where you enter the argument before
pressing the function key, for example, x
