I am not a fundamentally mean person, but when someone tells me, "I am bad at math" I have to suppress a chuckle.
Mathematics, at its core, is about problem solving - your skill at math directly translates to your ability to solve problems for your entire life. Accounting for unknowns, looking at things from a different angle, deconstructing an issue layer by layer... and, unless you make enough dough to pay for your future house cash, you are going to need to know some motherfucking geometry to build and maintain your own house!
At a most basic level, claiming that you are bad at math is tantamount to claiming that you have difficulty feeding yourself. I'm in agreement with this video.
