I want to create a sheet where there is a few math problems.

Example:

1+1 or 2+4.

And then below it is a box to fill in. You fill in the box and it pops up with a correct or wrong error.

At the end, I would need to show the entire page with all of the answers.

I also need a place where they can carry over the number. for example if it were 19+35.

How do I do this?

I need to do it in JavaScript.

Thanks!
