Answer 1

You need to return values from your which() function

function which() {
if( b == "add" ){
return sum(p) ;
} else if ( b == "multiply") {
return mult(p);
} else {
return "sorry i cant do that";
}
}

console.log(which())

Answer 2

You already have that set up, what do you mean?
If 'add' is entered at the 2nd prompt then b == "add" is true and the sum(p) function will run. Same for mult. If something else is entered then it will output the else.

Answer 3

You're doing good then! Keep it up!

Answer 4

Made more sense in this case

Answer 5

Global Universe
That's what I was trying to tell you in my first post. You should change the else statement to return the string instead of calling console.log() on it, and you should also parseInt(p) before sending it to the functions, so it is doing an implicit conversion.

Answer 14

I think I'm stuck kindly correct it for me I'm freaking confused right now😂😂

Answer 15

let num = parseInt(prompt("Enter a positive number"));

let op = prompt("Enter add or multiply");

function sum(n) {
//Gauss formula for sum of 1-n
return (n+1)*n/2;
}

/*function mult(n) {
let product = 1;

for(let i = 1; i <= n; i++) {
product *= i;
}
return product;
}*/

function mult(n) {
if (n == 1)
return 1;
else
return n * mult(n-1);
}

function which() {
switch (op) {
case "add":
return "sum: " + sum(num);
break;
case "multiply":
return "product: " + mult(num);
break;
default:
return "Invalid option";
}
}

console.log(which());

Answer 16

I've noticed you opted for swtch statements instead of if statements is there special reason?

Answer 17

True if statements are a bit tricky in this situation

Answer 18

I've put them and it works now

Wow I'm elated😁
