## Arithmetic (Basic Operations)

- All four basic arithmetic operations are supported by C++:
  - Addition and subtraction: `+ -`
  - Multiplication and division: `* /`
- Multiplication and division bind more strongly than addition and subtraction.
- Use parentheses to indicate the order in which the subexpressions should be evaluated.

  > | `a + b / 2`
  > | `( a + b ) / 2`
