When an expression is evaluated successfully from the home screen or from a program,
the TI-84 Plus 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-84 Plus,
the value in Ans is retained in memory.
