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 2
π
, 2A, etc.
6
Single calculation functions that are irnmediately after a numerical value (sin, cos,
tan, sin -1 ,cos -1 , tan -1 , log, 10 x ,In, e x ,
◊
,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)
