Actually, according to this webpage of the Math Department, University of Warwick, you can gain not only math skills, but also a lot of other essential skills too:
Mathematical Skills. As a mathematics student you will study each of the major subject areas of modern mathematics: algebra, analysis, geometry, statistics, and applied mathematics. In the course of this study you will learn:
- The language of mathematics and the rules of logic.
- How to state a mathematical idea precisely.
- How to prove or disprove a mathematical conjecture.
- How to extract meaning from mathematics on the written page.
- How to use mathematics to describe the physical world.
Analytical Skills. Having done a Mathematics Degree, you will never again be able to tolerate sloppy reasoning. Mathematics will enhance your ability to:
- Think clearly.
- Pay attention to detail.
- Manipulate precise and intricate ideas.
- Follow complex reasoning.
- Construct logical arguments and expose illogical ones.
- Formulate a problem in precise terms, identifying the key issues.
- Present a solution clearly, making your assumptions explicit.
- Gain insight into a difficult problem by looking at special cases or sub-problems.
- Be flexible, and approach the same problem from different points of view.
- Tackle a problem with confidence, even when the solution is not obvious.
- Seek help when you need it.
- Looking up lecture notes, text books and reference books.
- Scouring the library.
- Searching databases for references.
- Extracting information from every mathematician you meet (other undergraduates, postgraduates, tutors and lecturers).
- Thinking!
- Listen effectively.
- Write mathematics well.
- Write essays and reports.
- Give a mathematical presentation to a group.
- Use e-mail and access the internet.
- Learn a programming language.
- Solve problems using mathematical software.
- Learn word-processing, of both text and mathematics.
- Be thorough and painstaking in your work.
- Organise your time and meet deadlines.
- Work under pressure, especially near exam time.
- Work independently, without constant support from teachers.
- Work co-operatively with others to solve common problems.
- Determination
- Perseverance
- Creativity
- Self-confidence, and
- Intellectual rigour.
