If you're interested in a basic math intro (starting from linear algebra concepts), check out Section 8.2 in this excerpt from the book "No Bullshit guide to Linear Algebra": https://minireference.com/static/excerpts/probability_chapte... This excerpt contains some exercises (with answers in the back) as well an examples application (PageRank).

Technically Linear Algebra is not "required" to understand Markov Chains, but it's a very neat way to think about them: each "step" in the chain is equivalent to multiplication of the state vector by the transition matrix.
