7-NS3

Solve real-world and mathematical problems involving the four operations with rational numbers. (Computations with rational numbers extend the rules for manipulating fractions to complex fractions.)

• 1 - Demonstrate computational fluency with addition, subtraction, multiplication, and division of integers.
• 2 - Use order of operations to evaluate numerical expressions.
• 2.3 - Applying laws of exponents to compute with integers.
• 3 - Solve problems requiring the use of addition, subtraction, multiplication, and division on rational numbers
