HP 9g Graphing manual Order of Operations

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-1, cos-1, tan-1, sinh,

cosh, tanh, sinh-1, cosh-1, tanh-1, log, ln, 10 X , e X, ,, NEG, NOT, X’( ), Y ’( ), MAX, MIN, SUM, SGN, AVG, ABS, INT, Frac, Plot.

2.Type A functions, that is, those where you enter the argument before

pressing the function key, for example, x 2, x 3, x-1, x!, º, r, g, %, º΄ ΄΄,
