Algorithms and Their Properties
What is an algorithm, who carries it out, and what properties must it have? Everyday examples help us meet the key ideas behind algorithms.

Flowcharts and Their Symbols
A flowchart shows an algorithm as a diagram, so its structure is easy to see. We learn what the main shapes mean and draw a chart for a simple calculation.

Executors and Command Systems
Who carries out an algorithm, and which commands does it understand? Using a simple robot, we study executors, command systems and the executor’s environment.

Linear Algorithms
In a linear algorithm every command is carried out in order, once. Using everyday and calculation tasks, we learn to write linear algorithms.

Finding and Fixing Errors in Algorithms
If an algorithm has a mistake, the executor gives a wrong result. We learn the kinds of errors and how to find them by testing by hand.
