Question

Evaluate the following expression as per Java priority & associativity.

49  − 28 − 4 * 3

Answer 1

Priority (Precedence): Multiplication (*) has higher precedence than subtraction (−), so it is evaluated first.

• 4 * 3: Multiplies first, giving 12. The expression becomes 49 − 28 − 12.
• 49 − 28: Subtraction operators share equal precedence and evaluate from left to right. This gives 21.
• 21 − 12: Subtraction is complete, giving a final answer of 9.
