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 AnsContinuing 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.
