* connecting different strategies for simplifying expressions with indices to illustrate the meaning of negative indices, expanding and simplifying results
* moving fluently between representations of numeric and algebraic terms with negative indices, and applying understanding of negative indices to calculations
* applying knowledge of index laws to algebraic terms, and simplifying algebraic expressions using both positive and negative integral indices
