GENERAL INFORMATION
9. Precedence of Calculations
• This unit is equipped with a function that detects calculation precedence.
• The calculation precedence is as follows:
1
Fraction calculations (a/b)
2
Complex angles (∠)
3
Single calculation functions immediately before a numerical value (X
2
, X
–1
, !, °,
r
,
g
).
4
Exponential functions (a
b
,
a
◊ etc.)
5
Multiplications with omitted “×” commands immediately before variables such as π or
stored memory and 2π, 2A, etc.
6
Single calculation functions that are irnmediately after a numerical value (sin, cos,
tan, sin

, ◊,abs, int, ipart, fpart, (–), not, neg etc.).
7
Multiplication with omitted “×” commands immediately before a single calculation
function that follows a numerical value (3 cos 20, etc.).
8
Permutation/combined functions (nPr, nCr)
