I'm working ahead of my daughter. They are working on checker tiles and out of the 20 packets I'm down to the last 3 that are giving me problems. They are situation tiles and it has been sorta like using algebra to figure them out. I want to help her out and know that she is getting them correct but I'm unable to answer them.
You can only use 0-9 once not including the numbers given to you already. I appreciate any help given.
