I have a cousin that is 16 years old, and cannot do simple math. She was over on Friday and we went grocery shopping, I was figuring out individual prices of something, for example 3 items for $7. I did the math in my head. She was shocked, so I started to test her. She doesn't know how to do simple math. Should the parents be held responsible because they don't give her the time at home to do homework? Is there something that can be done?
