Before you start using your calculator you should probably check the settings. To do that, go to mode. The default settings are all the settings that on the left side in this screen. I can see that for the second option here it's not at the default setting. So, I'm going to change that. I'm going to use the down arrow key The cursor is now where I want it. I'm going to press enter. I'm going to use the down arrow key again. press enter Now all the settings are what I need for this class. I'm going to quit and move to a home screen. So, second quit and I'm ready to get started
