■ Variables
● There are nine variables (A through F, M, X and Y), which can be used to store
data, constants, results, and other values.
● Use the following operation to delete data assigned to a particular variable: 0
SHIFT STO A . This operation deletes the data assigned to variable A.
● Perform the following key operation when you want to clear the values
assigned to all of the variables.
SHIFT CLR 1 (Mcl) =
● Example: 193.2 ÷ 23 ＝ 8.4
193.2 ÷ 28 ＝ 6.9
193.2 SHIFT STO A ÷ 23 =
ALPHA A ÷ 28 =
Scientific Function Calculations
● Use the COMP mode for Scientific Function calculations.
● Certain types of calculations may take a long time to complete.
● Wait for the result to appear on the display before starting the next calculation.
● π= 3.14159265359
■ Trigonometric/Inverse Trigonometric Functions
● To change the default angle unit (degrees, radians, grads), press the MODE
MODE. Press the number key（ 1 , 2 or 3 ）that corresponds to the angle
unit you want to use.
（90˚=π/2 radians = 100 grads）

■ Angle Unit Conversion
● Press SHIFT DRG► to display the following menu.
● Pressing 1 , 2 or 3 converts the displayed value to the corresponding
angle unit.
● Example：To convert 4.25 radians to degrees.
MODE MODE 1 →（D）
4.25 SHIFT DRG► 2 ( R ) =
■ Coordinate Conversion (Pol (x , y) , Rec (r , θ) )
● Calculation results are automatically assigned to variables E and F.
● Example 1: To convert polar coordinates（r = 2,θ=60˚）to rectangular
coordinates(x , y) (Deg).
x =1 SHIFT Rec ( 2 , 60 ) =
y=1.732050808 RCL F
● Press RCL E to display the value of x ,or RCL F to display the value of y .
● Example 2: To convert rectangular coordinates（1, √3）to polar coordinates(r
,θ) (Rad).
r=2 Pol ( 1 , √ 3 ) =
θ=1.047197551 RCL F
● Press RCL E to display the value of r or RCL F to display the value of θ.
■ Engineering Notation Calculations
● Example 1: To convert 56,088 meters to kilometers
