2F : Appears when the second function
has been selected.
HYP : Appears when the hyperbolic function
has been selected.
( : Appears when you press [ ( ]. It shows
the present level of nesting.
ORDER OF OPERATIONS
Each calculation is performed in the following order of precedence:
1) Functions required inputting values before pressing the function
key, for example, cos, sin, tan, cos
–1
, sin
–1
, tan

, log, ln, x
2
, 1/x,
Ѕ, Ӹ,
3
, X!, %, , and 13 units conversion.
2) Operation in parenthesis
3) Functions required pressing the function key before entering, for
example, [ EXP ] key .
4) Fractions
5) +/–
6)
