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 E& 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 Gig key before starting any new

calculation.

Example 1: 2 x (3 + 4) =

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 entered first

and then the function key is pressed)

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

2) Powers, roots

CoN

Coordinate conversions

R-P, PR

Permutations, conbinations

. aPr, nCr

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

and then the value is entered).

Vv, Vv, log, In, €*, 10%, sin, cos, tan, sin~" , 60s"?

tan~', sinh, cosh,-tanh, sinh7', cosh" , tanh",

NOT {in the BASE-N Mode) -

(4) Multiplication, division ineand constant calcula-

tions)

=X, +.

*When functions with the same priority sequence are

used in series, they_are executed from right to left

[eXInv120-e* | in(v:120)}]. Other expressions of the

nang priority sequence are performed from left to

right
