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

, X
–1
, !, °,

,
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

7 Multiplication with omitted “×” commands immediately before a single calculation
function that follows a numerical value (3 cos 20, etc.).
