2/BEFORE BEGINNING CALCULATIONS

Formula

Input (V.P.A.M. System)

The V.P.A.M. System of this calculator lets you sim-

ply input a formula just as it is written, and then press

the Eq key to obtain the result. The execution of

arithmetic operations, functions and expressions wi-

thin parentheses are automatically performed in the

correct priority sequence.

*Be sure to press the Gg key before starting any new

calculation.

Example

1: 2 x (3 + 4) =

GS 2E3

J 3G9

Example 2: sin30 = 0.5

@ Calculation Priority Sequence

The calculation priority sequence is used in mathemat-

ics to decide which operation should be performed first.

This calculator automatically assigns the calculation

priority sequence shown below.

(1) Type A Functions (where the value is ente7ed first

and then the function key is pressed)

x', x', x!, NEG (in the BASE-N Mode)

2) Powers, roots

Coordinate conversions

ROP,

P>R |

Permutations, conbinations

nPr, nCr

(3) Type B Functions (where the function key is Pee

and then the value is entered).

(4) Multiplication, division ineludsg constant calcula-

tions)

6) Addition, subtraction (including constant Calcula-

tions) - is cs

@) OR, XOR, XNOR-- z

*When functions with the same priority sequence are

used in series, they_are executed from right to left

[e'Inv120—e" { In¢v:120)}]. Other expressions of the

ty 'priority sequence are performed from left to

} In the BASEN Mode
