[. . . ] Number Line gives a dynamic, electronic representation of a 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 also see where the ending point (result of the expression) falls on a number line. [. . . ] • ZoomFit adjusts Min and Max so that all vectors in the current expression are displayed within the viewing screen. If you have entered a large range of numbers, all vectors may not fit the viewing window. • ZStandard returns the window to the default settings: Min=L20, Max=20, Scale=2, Start=0, LabelOff. To exit ZoomFit or ZStandard, press the * key, or press - l.

To exit ZoomFit or ZStandard, press *, or press - l. Number Line/Fraction Line for the ECLATEE ARIANE 30 Page 27 Drawing Labels on the Fraction Line Use DRAW to label numbers along the number line. • Scrolling an indicator outside of the window settings displayed on the screen or entering a new value for the indicator also clears the labels. To exit DRAW without making any changes, press the * key, or press - l. Number Line/Fraction Line for the ECLATEE ARIANE 30 Page 28 2. Continue labeling numbers at this prompt. Note: If you label numbers that are very close together, the labels may overlap each other when they display. 3. When you are finished, press b at the Label= prompt to exit labeling mode. The Fraction Line screen displays, showing labels for each number you entered. Note If you specify a number outside the window range, it will not be labeled.

Instead, convert from fraction to decimal and then to percent. ) • Press B to convert an unsimplified fraction to its simplified form. Value = 25 > converts it to fraction. > converts it back to decimal.
