Multiplying Strings?

I didn't see parseInt() in your code, but you certainly raise an
interesting point.

So far, so good. You've declared two String variables and have clearly
supplied them with String values.

> this.theAnswer = this.tenStr*this.fiveStr;

In this line, the * operator "sees" two numbers, so it multiplies them.
I know you typed them as Strings, but keep in mind: the (so-called) strong
typing in AS2 is not *true* strong typing. In AS2, the post colon suffix is
only checked during the compile process. At compile time, vars tenStr and
fiveStr are, in fact, strings.

If either variable had had any characters besides numerals, the result
of your multiplication would be NaN, as expected.
