How do you use a mouse?

Answer 1

Use the mouse as a point and click device. Watch the monitor as you move the mouse around and you should see an arrow moving on the window/screen in relationship to the motion of the mouse.

Now move the mouse so that the corresponding arrow you see on the Graphical User Interface (aka GUI~aka what you see on the computer's monitor screen) is placed on the desired location (e.g., the button you want to click or highlighted item you want to select) of the interface (e.g., on the button or item on the monitor that you want to click) and then clicking the left mouse button on the mouse to select the (usually highlighted) item or button on the screen.

The left mouse button is used more often and to click to take actions as described above, but when you click on the right mouse button, it allows you to see a menu of other actions you can use the left mouse button to select (such as copy, delete, move, print, etc.). The actions you can choose on that menu will sometimes change depending on where you are hovering the arrow on the screen.

There are many games for practicing mouse use and other demonstrations of how to use a mouse available online. See the link in the related links section for a demo from Microsoft on how to use a mouse.
