This combination of written and programmed exer- cises is meant to cement your understanding of how computers “see” and “work with” the information that we use everyday.

Remember that absolute accuracy is required — this code must be entered exactly as shown (at least until you’ve gained a little more experi- ence and knowledge on the subject): var a = "Hello"; var b = "World"; alert(a + b); var i = 1; var j = 1; alert(i + j); var c = "1"; var d = "1"; alert(c + d); var x = 1.5; var y = 3.25; alert(x + y); alert(i + j + a + b + c + d + x + y); What happens when you run this program? For each alert command (there are five of them), explain what you think the computer is doing with the expression that is being “alerted.” 3. Do the following exercises from Chapter 2 of the Brookshear book: a. Question 3 on page 82 b. Questions 1 and 2 on page 88
