Have fun going broke because you don't know how to manage your finances.
... I don't think I've used -- or needed -- a single thing more advanced than very basic algebra in regards to
anything related to financing. You don't need more than basic understand of the concept and use of variables to basically master friggin'
accounting, never mind basic lifestyle finance management.
And beyond that, not a single bloody
one of the math classes I've taken -- not even the freaking one
on business related math -- had jack all in regards to actually teaching you how to use any of it in a practical way. Not a damned thing outside some halfhearted budgeting exercises and poorly framed examples
So no. People aren't going to learn to manage their finances in math class, unless the curriculum has radically changed recently. Above and beyond
that, math in general does fuck all to genuinely help you manage your finances to begin with -- it lets you track the numbers better, but that does
nothing for your decision making or long and short term planning ability in and of itself. Math facilitates financial planning, but it does not enable it.
Call it something of my own personal annoyance. Getting annoyed about people getting annoyed about being taught math that has no direct use for them -- and worse, not even taught how to actually goddamn use what they
can use -- annoys me. Don't get annoyed at them -- get annoyed at the either the idiots who are teaching them or the greater idiots that have forced non-idiots to teach poorly.
