Arithmetic Operators Quiz: Test Your Java Skills (AP CS A)

📚 Quick Study Guide

🔢 Arithmetic Operators: Used to perform mathematical calculations. ➕ Addition (+): Adds two operands. Example: $5 + 3 = 8$ ➖ Subtraction (-): Subtracts the second operand from the first. Example: $5 - 3 = 2$ ✖️ Multiplication (*): Multiplies two operands. Example: $5 * 3 = 15$ ➗ Division (/): Divides the first operand by the second. If both are integers, the result is an integer (truncating any decimal part). Example: $5 / 2 = 2$ 💯 Modulus (%): Returns the remainder of the division of the first operand by the second. Example: $5 % 2 = 1$ 💡 Integer Division: When dividing integers, Java truncates the decimal part. For example, $7 / 2$ results in $3$. 📈 Operator Precedence: Multiplication, division, and modulus have higher precedence than addition and subtraction. Use parentheses to override precedence.
