1 - 1 Before Starting Calculations...
kMemory Capacity
Each time you press a key, either one byte or two bytes is used. Some of the functions that require one byte are: b, c, d, sin, cos, tan, log, In, 
, and π. Some of the functions that take up two bytes are d/dx(, Mat, Xmin, If, For, Return, DrawGraph, SortA(, PxIOn, Sum, and an+1.
When the number of bytes remaining drops to five or below, the cursor automatically changes from “ _ ” to “ v ”. If you still need to input more, you should divide your calculation into two or more parts.
• As you input numeric values or commands, they appear flush left on the dis- play. Calculation results, on the other hand, are displayed flush right, except in the ALGBR Mode.
kGraphic Display and Text Display
