1.1.3 Keeping the calculator running on your Windows desktop
When performing a number of calculations whilst using other programs on your computer, it's convenient to keep the calculator running in the background.
To do this click on the 'Minimise' button of the calculator's window (the leftmost button in the top right corner). When you are ready to start working with the calculator again, click the 'Calculator' button in the Windows taskbar. (The taskbar is usually at the bottom of the screen; it contains the 'Start' button.)
