Computation with Variables Corresponding Material Basic JavaScript, Lesson 4 Exercises: T-Shirt Shop, Running Speed Discussion Variables are not only useful because they store values. We can use variables to perform operations like addition, subtraction, and multiplication. In this handout, we’ll create a few variables and use them to perform some basic computations. Exercise Let’s create a few variables to work with. What’s your favorite number? var favoriteNumber = _____ ; On what day of the month were you born? var dayOfBirth = _____ ; How many books have you read this year? var numBooksRead = _____ ; Lastly, we’ll create an answer variable to store the results of our computations. var answer = 0; Now, fill in the blanks in the table below! Step Pseudocode Answer Add day of birth and books read, assign the result to the answer variable Subtract the favorite number from the value of answer, store the new result in the answer again Multiply answer by the day of birth, store the value in the answer variable Subtract the number of books read from the answer and assign this value to the answer variable What’s your total answer? _____________
