How would I make a factorial calculator function? I need that to make a permutations and combinations calculator. I am pretty sure you would need a loop of some sort, but I'm not sure how to do it. Thanks for the help!

factorials: n × (n - 1) × (n - 2) ... 2 × 1

you can try using for loop variable to start at n and go to 1 and get something to hold the product of the multiplication inside the loop

n

1

Wdym?

How do get the number of numbers before hitting 1?

let product = 1; for (let i = 0; i < n; i++) { product *= i; }

Is n the number ur "factorialing" by?

Hmm, it's not working.

Try it ur self.

@mwilki7this is how you can implement the factorial function on your calculator

@mwilki7Is n the number ur "factorialing" by?

@mwilki7yes, if i want to find the factorial of 5, n would be 5

Hmm, it's not working.

@mwilki7what are the results you are getting

Try it ur self.

@mwilki7shoot how did i miss that
