A basic calculator performs the four fundamental arithmetic operations: addition (+), subtraction (−), multiplication (×), and division (÷). Order of operations (BODMAS/PEMDAS) determines calculation sequence when multiple operations appear: Brackets, Orders, Division/Multiplication, Addition/Subtraction.

Trinn-for-trinn guide
- 1Addition: combining two quantities — commutative (a+b = b+a)
- 2Subtraction: finding the difference — not commutative (a−b ≠ b−a)
- 3Multiplication: repeated addition — commutative (a×b = b×a)
- 4Division: splitting into equal parts — not commutative (a÷b ≠ b÷a)
- 5BODMAS: Brackets → Orders (powers/roots) → Division/Multiplication → Addition/Subtraction
