Answer Memory (Ans) /Previous Answer Memory (PreAns)

The last calculation result obtained is stored in Ans (answer) memory. The calculation result obtained prior to the last one is stored in PreAns (previous answer) memory. Displaying the result of a new calculation will move current Ans memory contents to PreAns memory and store the new calculation results in Ans memory. PreAns memory can be used only in the COMP Mode. PreAns memory contents are cleared whenever the calculator enters another mode from the COMP Mode.

To divide the result of 3 4 by 30 b

3 *4 =

(Continuing) /30 =

123 + 456 = 579 B 123 +456 =

789 – 579 = 210

(Continuing) 789 -G=

For Tk+2 = Tk+1 + Tk (Fibonacci sequence), determine the sequence from T1 to T5. Note however, that T1 = 1 and T2 = 1. B

T1 = 1

1 =

(Ans = T1 = 1)

T2 = 1

1 =

(Ans = T2 = 1, PreAns = T1 = 1)

T3 = T2 + T1 = 1 + 1

G+SG(PreAns)=

(Ans = T3 = 2, PreAns = T2 = 1)

T4 = T3 + T2 = 2 + 1

=

(Ans = T4 = 3, PreAns = T3 = 2)

T5 = T4 + T3 = 3 + 2

=

Result: The sequence is {1, 1, 2, 3, 5}.
