k Calculation Priority Sequence
The calculation priority sequence is the order that the calculator performs opera-
tions. Note the following rules about calculation priority sequence.
•Expressions contained in parentheses are performed first.
•When two or more expressions have the same priority, they are executed from
right to left.
Example 2 + 3 × (log sin2π
2
+ 6.8) = 22.07101691 (angle unit = Rad)
The following is a complete list of operations in the sequence they are performed.
1. Coordinate transformation: (Pol (
x, y), Rec (r,
θ
); differential calculations: d/dx(;
List: Fill, Seq, Min, Max, Mean, Median, SortA, SortD
2. Type A functions (value input followed by function):

3. Powers: ^ (

4. Fraction input: a

5. Multiplication operations where the multiplication sign before π or a variable is
omitted: 2π; 5A; 3sinx; etc.
6. Type B functions (function followed by value input):

7. Multiplication operations where the multiplication sign before a scientific function
is omitted: 2
3; Alog2; etc.
8. Permutation: nPr; combination: nCr
9. Multiplication; division; integer division; remainder division
10. Addition; subtraction

k Using Multistatements
Multistatements are formed by connecting a number of individual statements for
sequential execution. You can use multistatements in manual calculations and in
programmed calculations. There are two different ways that you can use to connect
statements to form multistatements.
• Colon (:)
Statements that are connected with colons are executed from left to right, without
stopping.
