EXPANDED ALGORITHM METHOD (numbers)

The concept of addition (with "carrying") can also be shown numerically in such a way to identify any numbers that need to be "carried" and why. This method is a great way to transition to the traditional method adding with "carrying". In fact, a transition does not need to be made and children can continue using this method and be very successful.
