Section 2.7 Arithmetic

• The arithmetic operators (p. 51) are + (addition), - (subtraction), * (multiplication), / (division) and % (remainder).

• Integer division (p. 51) yields an integer quotient.

• The remainder operator, % (p. 51), yields the remainder after division.

• Arithmetic expressions must be written in straight-line form (p. 51).

• If an expression contains nested parentheses (p. 52), the innermost set is evaluated first.

• Java applies the operators in arithmetic expressions in a precise sequence determined by the rules of operator precedence (p. 52).

• When we say that operators are applied from left to right, we’re referring to their associativity (p. 52). Some operators associate from right to left.

• Redundant parentheses ...
