When an expression is evaluated successfully from the home
screen or from a program, the TI-82 STATS stores the answer to
a storage area called
Ans (last answer). Ans may be a real or
complex number, a list, a matrix, or a string. When you turn off
the TI-82 STATS, the value in
Ans is retained in memory.
You can use the variable Ans to represent the last answer in most
places. Press y [
ANS] to copy the variable name Ans to the
cursor location. When the expression is evaluated, the
TI-82 STATS uses the value of
Ans in the calculation.

total of 147 tomatoes.

You can use Ans as the first entry in the next expression without
entering the value again or pressing y [
ANS]. On a blank line
on the home screen, enter the function. The TI-82 STATS pastes
the variable name
Ans to the screen, then the function.

To store an answer, store Ans to a variable before you evaluate
another expression.
