1) Arithmetic operations like addition, subtraction, multiplication and division are fundamental to computer programs and involve performing calculations with variables of different data types. 2) Assignment statements are used to perform arithmetic operations and convert values between different variable types, allowing data to be reused in further calculations. 3) Variables storing operation results can be used in multiple places, with hierarchical operations following mathematical order of operations unless parentheses specify a different sequence.

1. Variables in Arithmetic OperationsGlenda Finley

3. Many programs require calculations with:

4. Addition

5. Subtraction

6. Multiplication

7. DivisionintTotal = intNumber1 + intNumber2 intNewBalance = intOldBalance - intNewOrder decTotal = intNumber * decCost decAverage = decScore/intNumberofScores

9. Converts value of a string of characters and copies to a specific type of variablestrNumber = Me.txtNumber.Text intNumber = Convert.ToInt32 (strNumber) Assigning data from textbox on form to a String variable Converting data from String variable and copying to an Integer variable

11. When a value is stored in a variable, it can be used in other places in the program.Variable used in one operation decTotalCost = decCost * decItems decTotalPrice = decTotalCost + decShipping Variable used again in second operation

13. Raising a number to a power

14. Integer Division

15. Quotient returned from division operation as an integer

16. Modulus Arithmetic (Remainders)

17. If division operation produces a quotient with a remainderintCube = intNumber ^ 3 intHours = intTotalMinutes 60 intMinutes= intTotalMinutes Mod 60

19. Sequence of calculations follows the basic mathematical rules

20. Calculations proceed from left to right

21. Using parenthesis in an expression ensures the sequence of operations to be explicitly clear
