 In computing, a <em>flag</em> is a type of signal usually used to indicate whether something is true or false. To save time and make your program less complicated, you might want to combine these flags and send several pieces of information in one go.
 
 Imagine you wanted to send a message to your friend to indicate which subjects had set homework on a particular day. If it was only one subject, you can just send the name of the subect - e.g. English - but if there is more than one, it gets more complicated. One way to do it is to give each subject a number:

 This means that each total can only be made up from one combination of subjects.
 
 If they'd been numbered as 1 = **English**, 2 = **Maths**, 3 = **Science**, 4 = **Computing**, etc., then it wouldn't work, because a code of 3 could represent English and Maths, or it could be Science on its own.
