1.2 Arithmetic Expressions

• What are arithmetic expressions composed of?

  Operands and operators
• What is the result of the subtraction '10 - 4'?

• What is the description of the multiplication operator '*' in Java?

  Multiplies two numbers
• What is the first operation performed in PEMDAS?

  Parentheses
• Ignoring PEMDAS in an expression like `3 + 4 * 5` results in the incorrect answer 35.

  8
• Match the arithmetic operator with its description:

  + ↔️ Addition

  ↔️ Subtraction

  * ↔️ Multiplication

  / ↔️ Division

  % ↔️ Modulus (remainder)
• The order of operations (PEMDAS) must be followed in Java arithmetic expressions.


  True
• What is the result of the Java expression 17 % 5?

  2
• What is the value of the Java variable quotient after executing the code: `double dividend = 20.0; double divisor = 4.0; double quotient = dividend / divisor;`?

  5.0
• What is the result of the Java expression 6 * 3?

  18
• The addition operator in Java is represented by '+'.


  True
• The modulus operator '17 % 5' results in 2.

  True
• Match the arithmetic operator with its description:

  Addition ↔️ Adds two numbers

  Subtraction ↔️ Subtracts the second from the first

  Multiplication ↔️ Multiplies two numbers

  Division ↔️ Divides the first by the second

  Modulus ↔️ Gives the division remainder
