A Simple Quiz of Arithmetic

Summary: Using a random number generator, we develop a simple quiz that tests student knowledge of arithmetic.

Prerequisites: Alert boxes, expressions, and forms.

Provides: A quick introduction to the use of random numbers

References: Random numbers in JavaScript, The JavaScript library random.js

Create a page with one button, Quiz Me, that asks the user to add two numbers between 1 and 20. Your page should check the user's answer.

• You'll need to load the random.js library.
• You can ask for an answer using a prompt() dialogue box.
• I'd suggest writing a function that loads the two numbers, produces the dialogue box, and checks the results. Then, your button tag can simply include something like onClick="doItAll()"
