Hi,
My son and I tried to answer a question with what we knew to be the correct answer and yet the computer did not accept it. We tried writing it several ways ( 16 cents, $0.16, and $ 0.16) to no avail.
We are a homeschool family that is trying to use Khan Academy as my son's math core this year, 4th grade.
Thanks!
