Be a Quiz Master! 🧠
Today YOU become the boss of a Math Quiz Challenge! 🎉
A quiz is just a list of questions. Let's build one with code! 💻
console.log('Welcome to the Math Quiz! 🧠')What Is a Question? ❓
A math question is something like 3 + 4. The computer can solve it super fast! ⚡
console.log('What is 3 + 4 ?')
console.log('The answer is', 3 + 4)Save the Question 📝
We can store a question in a variable so we can use it later.
let question = 'What is 5 + 2 ?'
console.log(question)Save the Answer Too 🔑
Every question needs a correct answer. Let's keep it in its own variable! 🔑
let question = 'What is 5 + 2 ?'
let answer = 5 + 2
console.log(question)
console.log('Secret answer:', answer)Make Many Questions 📚
A good quiz has lots of questions. We can make a whole bunch! 📚
console.log('Q1: 2 + 2 =', 2 + 2)
console.log('Q2: 6 - 1 =', 6 - 1)
console.log('Q3: 3 * 3 =', 3 * 3)Use a List 📋
We can put all our questions in an array (a list). Lists keep things tidy! 📋
let questions = ['2 + 2', '6 - 1', '3 * 3']
console.log(questions)Random Numbers 🎲
To make NEW questions every time, we use Math.random() to pick random numbers! 🎲
let a = Math.floor(Math.random() * 10)
let b = Math.floor(Math.random() * 10)
console.log('Your question:', a, '+', b)Random Question + Answer ✨
Now let's make a random question AND know its answer! ✨
let a = Math.floor(Math.random() * 10)
let b = Math.floor(Math.random() * 10)
let answer = a + b
console.log('What is', a, '+', b, '?')
console.log('Answer:', answer)Different Math Signs ➕➖
Questions can use +, -, or *. More fun, more challenge! 💪
let a = 8
let b = 3
console.log('Add:', a + b)
console.log('Subtract:', a - b)
console.log('Multiply:', a * b)Number the Questions 🔢
Let's show Question 1, Question 2 so players know where they are! 🔢
console.log('Question 1: 4 + 4 =', 4 + 4)
console.log('Question 2: 9 - 3 =', 9 - 3)Your Mini Quiz 🎮
Put it all together: a couple of questions with their answers ready to go! 🎮
console.log('Math Quiz Time! 🧠')
console.log('Q1: 5 + 5 =', 5 + 5)
console.log('Q2: 7 * 2 =', 7 * 2)
console.log('Good luck! 🍀')Quick Check ✅
