Recalling and Storing the Last Answer
-
¢
When an expression is evaluated successfully from the Home
screen or from a program, the TIN73 stores the answer to a
system variable called
Ans
(last answer). Recall
Ans
by
pressing - ¢.
Ans
can be a real number or a list. When you
turn off the TIN73, the value in
Ans
is retained in memory.
You can use the variable
Ans
in any place that is appropriate
for the type of answer
Ans
represents. For example, if
Ans
is a
real number, you can use it anywhere where real numbers are
accepted (Y= editor,
WINDOW
, List editor, etc.).
Continuing a Calculation with Ans Continuing a Calculation with Ans
You can recall
Ans
as the first entry in the next expression
without entering the value again or pressing - ¢. After
completing a calculation, press an operation or function key
(excluding <, =, or @) and the calculator displays
Ans
and uses the value in the next calculation.
