Understanding the common arithmetic operators

• What does the `*` operator do in arithmetic operations?

  Multiplication
• The example `16 % 5 = 1` demonstrates the use of the modulus operator.
• The `%` operator calculates the remainder
• What is the result of 15 / 3 using the division operator?

  5
• What are arithmetic operators used for in programming?

  Basic mathematical operations
• The `/` operator is used for division
• Match the arithmetic operator with its corresponding description and syntax:

  1️⃣ `+` | Addition | `x + y`

  2️⃣ `-` | Subtraction | `x - y`

  3️⃣ `*` | Multiplication | `x * y`

  4️⃣ `/` | Division | `x / y`

  5️⃣ `%` | Modulus | `x % y`
• In arithmetic operations, what are the values or variables being operated on called?

  Operands
• What does the modulus operator calculate?

  The remainder
• Order the steps of the standard order of operations (PEMDAS).

  1️⃣ Parentheses

  2️⃣ Exponents

  3️⃣ Multiplication and Division (left to right)

  4️⃣ Addition and Subtraction (left to right)
• What is the result of 15 / 3 - 1 following the order of operations?

  4
• The subtraction operator is represented by the symbol -
• Division is performed before multiplication in PEMDAS.

  False
• The `+` operator is used for addition
• What does the `%` operator calculate?

  The remainder
• What is the result of `5 + 3` using the `+` operator?

  8
• What is the result of 5 + 3 using the addition operator?

  8
• The subtraction operator is represented by the symbol -
• What is the result of (5 + 3) * 2 following the order of operations?

  16
• Using parentheses can clarify and control the order of operations
• What is the result of 16 % 5 using the modulus operator?

  1
• The `-` operator performs subtraction in programming.


  True
• Arithmetic operators include addition, subtraction, multiplication, division, and modulus.


  True
• The expression `15 / 3` using the `/` operator results in 5.


  True
• The multiplication operator is represented by the symbol *
• The division operator always returns an integer result.

  False
• Multiplication and division are performed from right to left in PEMDAS.

  False
• Match the arithmetic operator with its description:

  Addition ↔️ Combines two values

  Subtraction ↔️ Finds the difference between two values

  Multiplication ↔️ Calculates the product of two values

  Division ↔️ Divides one value by another
• The order of operations is crucial for ensuring calculations are performed correctly.
