Precedence Of Calculations - Sharp EL-9650 Operation Manual

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
4
Exponential functions (a
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 -1 ,cos -1 , tan
7
Multiplication with omitted "×" commands immediately before a single calculation
function that follows a numerical value (3 cos 20, etc.).
8
