What is Number Line / Fraction Line?
This application contains two parts:
Fraction Line
Number Line
number line. It includes three data representations — an entry
line, a vector history, and the number line itself with an indicator
showing the current position of the entry.
Use Number Line when you want to create a numerical
expression by adding and/or subtracting positive and/or negative
whole numbers. You can then view the vector history. You can
also see where the ending point (result of the expression) falls
on a number line. As you edit an entry, the vector history and
ending point adjust, as necessary.
Fraction Line
double-sided number line. Each side of the number line may be
configured to represent numbers as decimals, fractions, or
percentages.
Use Fraction Line when you want to label a number line with a
fraction, decimal, percent, or whole number. You can then use
the labels to compare between many types of numbers at the
same time.
