Upon successful completion of this course students will be able to:

• Choose and perform accurate beginning algebraic computations in a variety of situations with and without a calculator.
• Solve problems at home or in an academic or work environment by creating a beginning algebraic expression or equation that represents the situation and find the solution to the problem using correct beginning algebraic steps.
• Recognize patterns in data collected or observed at home or in an academic or work environment and use the observed patterns to make predictions.
• Creatively and confidently apply beginning algebraic problem solving strategies. 
•  Be prepared for future course work.
