1. Reason abstractly and quantitatively. 2. Look for and express regularity in repeated reasoning. 3. Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If p and q are integers, then -(p/q) = (-p)/q = p/(-q). Interpret quotients of rational numbers by describing real-world contexts. 4. Solve real-world and mathematical problems involving the four operations with rational numbers.
