Split a bill
A $150 dinner for 6 people: how much does each person pay?
Step by step
- Click the Start button! Look at the bottom of this practice computer: the dark strip there is its taskbar. In the middle of it, click the Start button (four blue squares). The main menu opens just above it. If you see two taskbars, use the one inside this page.
- Click "Calculator". In the menu that opened, click the "Calculator" tile (a square with a small picture and its name under it): the app opens in its own window.
- Calculate 150 ÷ 6. In the Calculator window, click the buttons 1, 5 and 0 one after the other (that makes 150), then the ÷ button (in the right-hand column of buttons, just above ×), then 6, and finally the blue = button at the bottom right. The answer, 25, shows at the top: each person pays $25.
- Close this window. You are done with this window, so close it: click the ✕ button at the top right corner of the "Calculator" window (on its title bar, the strip at the top). The window disappears.
These steps are written for SafePC, a pretend Windows-style computer in your web browser. On your own computer, the buttons and menus may look a little different, but the idea is the same.
Practice it where nothing can break
SafePC works like a real computer, but nothing you do goes anywhere. Try every button, make mistakes and start again.
