2 Casio FX-570ES One-Page Wonder INTRODUCTION Welcome to the world of Casio s Natural Dislay scientific calculators. Our exeriences of working with eole have us understand more about obstacles eole face adating to a new scientific calculator, or any ICT tool for that matter. The most revalent issue is how to get started using the tool in the shortest time ossible. This is esecially true as the scientific calculator gets more sohisticated; yet eole have less time to learn its many functions through the user manual even it is extremely comrehensive. To resolve this issue, we came u with this one-age exercises idea. The key idea is to design a series of exercises where each exercise should be just 1-age long and is indeendent of each other. One imortant criterion of the design is that we want you to be able to use any one of these exercises with the calculator immediately, regardless of your calculator skill s level. Just as imortant is that each exercise must be short, functional yet not too comlex to use. So, based on the design rinciles just described we are roud to resent to you the FX-570ES One Page Wonder. You can begin using this resource by first look u the LIST OF EXERCISES in next age and find the exercise which suits your needs. The age number of each exercise is given at the middle column of the list. You can make coies of any of the activities for your class, share it with your friends, or just use them yourself. We would like to stress that the oneage exercise is not a relacement of the user guide that comes with your calculator but rather to serve as a sulement to it. Please write to us at info@qed-edu.com if you have any comments or ideas. We love to hear from you. Mun Chou, Fong QED Education Scientific Sdn. Bhd. All Rights Reserved.

Secial Notes for User of FX-350ES, FX-570ES and FX-991ES: The FX-ES calculator has a setting area (ta q w) where we can make referred settings. When we get unexected calculation outut from the calculator, usually it is due to inaroriate setting. It can easily be resolved: ta q w, check the current setting, and make the change. With list based statistics there is no need to reset STAT mode memory. However, the STAT setting now becomes quite imortant. For examle, if Frequency is turn ON, then you would see FREQ column aears and this affects your data entry rocess and subsequently the outut will be too. Therefore each time you start using STAT mode, it is generally a good ractice to clear the Setu by taing q 9 1 ; alternatively, you can check the STAT setting through q w R 4 and make the change.
