Quick-Start

Welcome to the world of color graphing calculators and the CASIO “CFX-9970G”.

Quick-Start is not a complete tutorial, but it takes you through many of the most com­mon functions, from turning the power on, to specifying colors, and on to graphing complex
equations. When you’re done, you’ll have mastered the basic operation of the “CFX­9970G” and will be ready to proceed with the rest of this user’s guide to learn the entire
spectrum of functions available.

Each step of the examples in Quick-Start is shown graphically to help you follow along
quickly and easily. When you need to enter the number 57, for example, we’ve indicated it
as follows:

Press fh

Whenever necessary, we’ve included samples of what your screen should look like.
If you find that your screen doesn’t match the sample, you can restart from the beginning
by pressing the “All Clear” button
