Final answer:
In Visual Basic, calculating two variables such as 'a' and 'b' involves using arithmetic operators. Code is written to define variables, perform an operation (such as addition), and output the result.
Step-by-step explanation:
To calculate two variables in Visual Basic, you can use simple arithmetic operations like addition, subtraction, multiplication, and division. Here is how you would write a code snippet to add two variables:
Dim a As Integer = 10
Dim b As Integer = 20
Dim result As Integer
result = a + b
Console.WriteLine("The sum of a and b is " & result)
This code defines two integer variables a and b, assigns them values, calculates their sum, and then prints the result to the console. You can replace the '+' operator with '-', '*', or '/' to perform subtraction, multiplication, or division respectively.
