Love this app!
I got this app years ago and I have never had a problem with it. I am surprised there aren’t more users. I teach math and have used it more than once for really large numbers.Seems broken

So happy to see an update to this handy little app. Helping my kids with math homework has been way easier since I downloaded it years ago. Thanks!
