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 T

= T

k+1

+ T

(Fibonacci sequence), determine the sequence

from T

to T

. Note however, that T

= 1 and T

= 1. B

= 1 1 =

(Ans = T

= 1)

= 1 1 =

(Ans = T

= 1, PreAns = T

= 1)

= T

+ T

= 1 + 1

G+SG(PreAns)=

(Ans = T

= 2, PreAns = T

= 1)

= T

+ T

= 2 + 1 =

(Ans = T

= 3, PreAns = T

= 2)

= T

+ T

= 3 + 2 =

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