He has never released his undergraduate grades, so his proficiency in math is hard to hard to evaluate. I have not read that he has any interest or proficiency in math or the physical sciences. I suspect he relies on others to make any difficult calculations that he might be interested in.
Since the president is responsible for the budget and for overseeing the economy, math is probably quite important. But it should be noted that because he is President, Mr. Obama does not do it all himself; he relies on a number of policy experts who do the calculations and estimates, and may even do some of the math. But he does have to understand mathematical concepts and relationships, including statistics, ratios, graphs, etc., in order to make use of the reports he he is given by his experts.
That's very open to debate.

He interprets the law.
He may, but he uses Youtube a lot.
When he was young, he liked to be called Barry; but he gradually began to use his real name (Barack) in college and no longer uses his nickname as far as we can tell.
