Programming - IGCSE Computer Science

a method for solving a problem set out as a series of step by step instructions with one start and one end

• algorithm
• arithmetic operator
• condition-controlled
• counter-controlled

a symbol that represents an operation in maths, the operation completes a calculation, the main operators are + -

• arithmetic operator
• condition-controlled
• counter-controlled
