( n )
: Appears when you press [SHIFT] [[X]] in the
program learn mode and when program
execution halts to let you enter a variable. The
number in brackets shows the number of the
place of the variable, and goes from 1 - 40.
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
–1
, log, ln, x
2
, 1/x,
√
, π,
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)
