Using the $+$ operator to paste together two strings can be very useful in building custom messages.

Suppose, for example, that you've calculated your savings want to summarize the results in a string.

To do this, you'll need to explicitly convert the types of your variables. More specifically, you'll need str$(),$ to convert a value into a string. str$($savings$),$ for example, will convert the integer savings to a string.

Similar functions such as int$(),$ float$()$ and bool$()$ will help you convert Python values into any type.
