1. The document contains a worksheet with math problems involving addition, subtraction, multiplication and division of integers. 2. Students are asked to solve multiple problems calculating the value of expressions with integers, find missing numbers in expressions, evaluate order of operations expressions, and rewrite expressions using order of operations. 3. The problems start simply and increase in complexity, covering basic arithmetic with integers up through more complex multi-step expressions requiring order of operations.
