3.Fractions: ab/c

4.Prefix symbol: (–) (negative sign)

d, h, b, o (base n symbol)

5.Metric conversion commands: cm'in, etc.

Statistical estimated value calculation: m, n, m1, m2

6.Permutations, combinations: nPr, nCr

Complex polar form symbol: ∠

7.Dot product: • (Dot)

8.Multiplication and division: ⋅, ⎟

Multiplication where sign is omitted: Multiplication sign omitted immediately before π, e, variables, scientific constants (2π, 5A, πA, 3mp, 2i, etc.), functions with parentheses (2'(3), Asin(30), etc.)

9.Addition and subtraction: +, –

10.Logical AND: and

11.Logical OR, XOR, XNOR: or, xor, xnor

If a calculation contains a negative value, you may need to enclose the negative value in parentheses. If you want to square the value –2, for example, you need to input: (–2)2. This is because x2 is a function preceded by a value (Priority 2, above), whose priority is greater than the negative sign, which is a prefix symbol (Priority 4).

Example:

–22= –4

y2w=

(y2)w=

(–2)2= 4

Multiplication and division, and multiplication where the sign is omitted are the same priority (Priority 8), so these operations are performed from left to right when both types are mixed in the same calculation. Enclosing an operation within parentheses causes it to be performed first, so the use of parentheses can result in different calculation results.

Example:

 

 

1

 

 

 

1/2i=

1

⎟ 2i =

 

i

 

 

 

2

 

1

 

1/(2i)=

1

⎟ (2i) = –

i

kStack Limitations

This calculator uses memory areas called stacks to temporarily store lower calculation priority sequence values, commands, and functions.The numeric stack has 10 levels and the command stack has 24 levels, as shown in the illustration below.
