Using Ans as a Variable in an Expression

Using Ans as a Variable in an Expression

Since

Ans

is a variable, you can use it in expressions just as

you would any other variable. When the expression is

evaluated, the TIN73 uses the value of

Ans

in the calculation.

For more information about variables, see the next two

sections in this chapter entitled, “Storing Values to a Variable”

and “Recalling Variable Values.”
