To clear all formulas:
Depress the QE , (TD , §Sf| @7] and SE keys.
Example 2: MULTIPLE FORMULA RESERVE
{When 4 kinds of formula are entered simultaneously:)
[Input]
Formula 1 — Circumference arsd area of a circle
/ = 2rrr S = trr2 r = 1,2,3
Note: The first value of the variable may be inputted directly follow^*
the variable sign.
Input Procedure: |5Sj H QjJ

Answer = 3.141592654
Formula 2 - Automatic Incrementing
To solve a formula in which the variable is increased by the same amount
each time, it is not necessary to place a value in the equation for each solu
tion. Place the amount to be incremented in Memory and each time |Sp|
is pressed the value of X will be automatically increased by the value in
memory.
