Ways to study mathematics while commuting I spend approximately 3 to 4 hours on public transport everyday. I try to maximize the usage of this time by checking email etc on my phone.
Are there any tips to study mathematics while commuting? 
Thanks for sharing! Just want to make full use of the time spent commuting!

Go to Amazon and search for whatever branch of mathematics you're looking for. Then change the order of the books to "average customer review" and you'll have a massively curated list of the best books in that topic.
