In this video, you will learn about the various arithmetic operators available in VBA (Visual Basic for Applications). Enter the world of basic and somewhat lesser-known operators, ranging from addition and subtraction to modulus and exponential operations. Understand their functions through clear examples, enabling you to conduct efficient calculations within your VBA code.

What will you learn

  • The fundamental arithmetic operators: addition, subtraction, multiplication, and division.
  • Understanding the modulus operator and its application.
  • Utilizing the exponential operator.
  • Practical examples to see how each operator works in VBA.
  • Importance of arithmetic operators in performing calculations within VBA code.

Takeaway notes

  • Addition (+): Combines two numbers to get their sum.
  • Subtraction (-): Subtracts the second number from the first to get their difference.
  • Multiplication (*): Multiplies two numbers to get their product.
  • Division (/): Divides the first number by the second to get the quotient.
  • Modulus (Mod): Returns the remainder after integer division.
  • Exponential (^): Raises a number to the power of another number.
  • Arithmetic operators are essential in conducting various calculations in VBA.
