​Logic Operators

​AND

​OR

​NOT

​A laptop computer has a ‘Battery low’ indicator that starts flashing red when the battery power falls below 20%, but only if the laptop is not charging.

​Remember to use the Logic Operators to work this out. Example: The Battery is below 20% AND the battery is Charging. This would make the Battery low flashing red True.

​Using the other logic operators.

​The battery is NOT below 20% AND the battery is NOT charging. This means the battery low flashing red would be FALSE.

​

The battery ​is below 20% AND the battery is NOT charging. This means the battery low flashing red would be TRUE

​They don't think for themselves.
