# Mathematics

Mathematics is the abstract deductive study of structure and pattern that serves as the foundation of science and technology. Transfer courses in mathematics emphasize the development of mathematical and quantitative reasoning skills beyond the level of intermediate algebra. Courses satisfy general education requirements for the Associate Degree for Transfer in Mathematics, and lower division transfer.

This discipline prepares students to do the following:

- Use proper vocabulary and notation when describing mathematical concepts; be able to read books and documents and extract quantitative information.
- Develop level-appropriate computational skills: numeric calculation, evaluation of expressions, analysis of data and application of concepts.
- Develop an understanding of, and curiosity toward the physical world.
- Develop the analytic skills to devise questions and propose quantitative solutions.
- Demonstrate computational skills and an understanding of mathematical reasoning that will increase self-esteem and set them on a path of lifelong learning.
- Be adept at using instructional software found by navigating the Web and the Windows environment.
- Perform mathematics functions at a level appropriate to the course. This “level” may range from arithmetic through differential equations and may include statistics, teacher prep and other topics.
