Show the Answer! 📣

Our calculator can store numbers, do math, and pick an operation. The last step is showing the answer in a NICE way! ✨

Let us make it friendly and clear for everyone to read.

Save Then Show 💾

First save the answer in a box called result, then print it!

let a = 5
let b = 3
let result = a + b
console.log(result)

A Full Sentence 💬

Let us show the whole math problem AND the answer together!

let a = 5
let b = 3
let result = a + b
console.log(a + ' + ' + b + ' = ' + result)

Add Some Sparkle ✨

Make the answer exciting with emojis and words!

let a = 8
let b = 2
let result = a * b
console.log('🎉 The answer is ' + result + '! 🎉')

Show Based on Choice 🎯

Let us combine if with showing! Pick an op, compute, and display nicely.

let a = 10
let b = 5
let op = 'add'
let result = 0
if (op === 'add') {
  result = a + b
}
console.log('Result: ' + result)

The Whole Calculator! 🧮

Here is our COMPLETE calculator! It picks the math and shows a clear answer.

let a = 12
let b = 4
let op = 'multiply'
let result = 0
if (op === 'add') {
  result = a + b
} else if (op === 'subtract') {
  result = a - b
} else if (op === 'multiply') {
  result = a * b
} else if (op === 'divide') {
  result = a / b
}
console.log(a + ' ' + op + ' ' + b + ' = ' + result)

Try Multiply 🔢

Change op to 'subtract' in the full calculator and watch the answer change!

let a = 9
let b = 4
let op = 'subtract'
let result = 0
if (op === 'add') {
  result = a + b
} else if (op === 'subtract') {
  result = a - b
}
console.log('Answer: ' + result)

Handle Mistakes 🛟

If the user picks a weird op, let us show a friendly oops message instead of a wrong answer!

let op = 'jellybean'
if (op === 'add') {
  console.log('Adding!')
} else {
  console.log('Oops! Please pick add, subtract, multiply, or divide. 🙂')
}

Decorate the Output 🎀

Add lines around the answer to make it stand out like a banner!

let a = 6
let b = 6
let result = a + b
console.log('=============')
console.log('Answer: ' + result)
console.log('=============')

Round Answers 🔵

Dividing can make long decimals! Math.round makes a neat whole number.

let a = 7
let b = 2
let result = a / b
console.log('Exact: ' + result)
console.log('Rounded: ' + Math.round(result))

Your Turn: Final Calculator 🌟

Change the numbers and the op, then run YOUR own calculator! You built this! 🏆

let a = 15
let b = 3
let op = 'divide'
let result = 0
if (op === 'add') {
  result = a + b
} else if (op === 'subtract') {
  result = a - b
} else if (op === 'multiply') {
  result = a * b
} else if (op === 'divide') {
  result = a / b
}
console.log(a + ' ' + op + ' ' + b + ' = ' + result)

Quick Check ✅

Final brain check! 🧠

Calculator Complete! 🎉
