Visual Formula appears after you set up the ratio. Here are the steps you take to
create it:
1. Click the Quotient menu item in the top menu list Visual Formula
provides. Then click in the upper equation composition area to position
the quotient bar.
2. Click the Value field menu item. To position the Value field, click just
above the quotient bar in the upper equation composition area. Once
again, click the Value field menu item, and this time when you position
the field, click just below the quotient bar.
3. Now name the two fields. Working in the equation composition area, in the
upper (numerator) field of your ratio, type
a
. In the lower (denominator)
field, type
b
.
4. Now move to the panel to the left of the equation composition area.
Beneath the Variable label, you see the names of sets of fields. In the top
Name field, type
a
. In the bottom Name field, type
b
.
5. To perform the divisions, begin by typing the numerator and denomi-
nator values in the Value fields you have set up in the right panel.
6. After you type the numbers, move to the other side of Visual Formula
and click the button with the equal sign. You see the result of the division
in the field to the right of the button.
Given this beginning, you can now enter new numbers in the Value fields you
have set up. Each time you do so, click the button with the equal sign. If the value
you enter is a repeating decimal, you see the set of repeating numbers. When you
type 1 and 17, for example, you see the following result:
0

Conclusion
In this chapter, you have reviewed basic number systems and some of the
properties relating to them. In addition to the commutative, associative,
and distributive properties of numbers, you have explored the additive and
