Enter the number that is 10 more than 642

This is a very hard question, so don’t feel bad you don’t know. Let’s see here.. 10 + 42 is 52 so add a 6 to the beginning to get 652. I hope it’s right!

No a triangle cannot be formed because when you add the two smallest number together (which would be 11) the have to be bigger than the number it is "against" ( which would be 12)
