This introduction covers The Tools of Calculation within Operators for GCSE Computer Science. Revise Operators in 3.2 Programming for GCSE Computer Science with 15 exam-style questions and 8 flashcards. This topic appears less often, but it can still be a useful differentiator on mixed-topic papers. It is section 2 of 7 in this topic. Use this introduction to connect the idea to the wider topic before moving on to questions and flashcards.
The Tools of Calculation
Operators are the verbs of programming - they DO things to data. Arithmetic operators do maths (+, -, *, /). Comparison operators ask questions (==, !=, <, >). Logical operators combine conditions (AND, OR, NOT). Master these and you can make computers calculate anything!
