It seems a large number of you believe most advanced math to be useless in everyday situations. I am disappointed.
I don't believe that math is as useless as you think. Math can be applied to many situations, from banking and money management (basically economics), to gambling and similar decision making (probability is very useful.) Many everyday uses of math involve the usage of formulas that you wouldn't realize exist because all you are doing is adding/subtracting/multiplying/dividing, even though technically you are solving an equation that is equal to x. Math gives you a greater understanding of what you are doing, allowing you to manipulate the "invisible" formula and solve for a different variable in the previous example.
In fact, while this probably isn't very useful, in my math book the other day there was a problem involving a formula for calculating how many people hear a rumor in "t" minutes. I bet that would be useful if you turned out to be a reporter or something, a job that most would believe requires no math at all.
Even estimation is something that everyone uses everyday and while that may not be "advanced" math, knowing how to do it is quite important.
There are formulas for everything! Traveling problems are solved with math (haha that classic train problem that everyone remembers?), wages, growth, you name it! One time I heard a story about someone who was riding their bike got hit by a car, and admitted to "maybe not looking" and they were said to be partly at fault. Well they went back and measured the skid marks and found the car to be speeding. There are so many uses of math, and I agree they are hard to think of, but they are out there.
