Does double majoring with math in undergrad help one grasp TCS topics more easier?

I'm a CS major. However, a lot of TCS topics seem to be in the realm of pure math. Should I add a math major to complement understanding and for a future career in TCS?

Solution

Three benefits of math classes:

Knowledge of particular mathematical topics that are useful in TCS. This is a bit specific to the circumstance, but of course it helps! Probability, combinatorics, algebra, sometimes analysis, number theory, logic, ....

Mathematical maturity, general comfort with proofs and mathematical reasoning. Very important.

Showing your qualifications on grad school applications.

But I think the specific classes you take and skills you gain are more important than whether you officially major in math or not.

+2 – @mathworker21 what is your question or comment? I think which classes are more useful varies throughout TCS. — May 11, 2022 at 02:31
