Chapter 1: Getting Started

When you reverse the keyboard, the following settings are automatically changed.

Basic → Advanced

• Simplifying: Auto (Auto at SIMPLE in SETUP menu)

Advanced → Basic

•Coordinate system: Rectangular coordinates (Rect at COORD in SETUP menu.)

•Answer mode: Displays a mixed number if ANSWER is set to complex numbers.

•Angle unit: Set to Deg if DRG is set to Grad.

•Decimal format: Set to FloatPt if FSE is set to Eng.

Quick Run-through: Basic Mode

Here are the major ingredients for 18 doughnuts:

1

4 cup warm water

3

4 cup warm milk

1

3 cup sugar

4 cups all-purpose flour

2 eggs

3 tablespoons butter

Based on these values, solve the following problems using the calculator.

Question If you make 60 doughnuts according to the above recipe, how many cups of warm milk are required?

At first, you may calculate how many cups of warm milk are required for 1 doughnut =

34 ÷ 18

As for the ordinary calculator, the answer is 0.041666666. But how much is 0.04166666 of a cup of warm milk? The Basic mode of this graphing calculator is initially set to the fraction answer mode instead of the decimal answer mode. You may easily obtain the answer in fraction.
