learning objectives
Tooltip content
to be able to use true and false (the two boolean values) to evaluate conditional statements.
success criteria
- I can define what True and False are.
- I can respond to a statement depends in if the statement is True or False.
top tips
- True values are positive, while False values are negative.
- Boolean values are only either True or False. They are named after the British mathematician George Boole.
Common misconceptions
- Answering 'True' and 'False' to statements is very straightforward.
- Sometimes answering these statements is difficult, because it is temping to answer 'True' or 'False' without paying attention to the wording of the statement. For example, the answer to the statement: 'It is not raining', is 'True' only if it is not raining.
Boolean Values
Boolean values express statements that could be either ‘True’ or ‘False’.
TOPIC BACKGROUND READING
Variables can hold many types of data, one type is called boolean. A boolean can only be True or False. It does not hold any other information.
In programming we refer to variables which can only have two possible states, True or False, as having the Boolean data type. This Boolean data type can be represented in different ways across the different programming languages. The most common
True and False are most commonly used as the answers to programmatic questions that need a definitive answer. They originate from circuitry and logic gates. A circuit is either flowing and On or not flowing and Off. By combining millions of these on/off switches, the computer can handle very complex calculations.
