But don't forget math can be used for more then weight loss.
Math is good in the grocery store to compare prices, figure out weight watcher points.
Depends on what you do, man. :-) And what your interests are. Now generally the only math everyone really need is enough to ballance your checkbook. But depending on what your interests are, it can be either a useless abstract discipline, or an extremly powerfull tool. Take me for example. I used what I learned in trig to invent my own 3d engine. I'm now at work at my first 3d game demo. Video games use all sorts of complex math, without it my game could not exist. Also I'm into diy video projectors. Built my own movie theatre projector. Just yesterday I was questioning the focal length of my spherical reflector, I used math to write a formula for the radius of the reflector and confirm the exact focal length and where to place the reflector. Lets see... me and my friend were splitting a polarizer sheet for our projectors, and I wrote a formula to calculate the dimensions of each piece for a given height or width (the size was limited thus the width was dependant on the height and vice versa) I've used math in.. baking tripple batches of cookies or making coffee (easy stuff) I helped my mom calculate how many calories she can have daily. Uh... what the odds are for winning the lotterly. Lots of stuff, I can't remember all of it. Theres so much cool stuff I did with math! My life would be so boring without it!
sir, i wuld like to know in details abt the role of mathematics in daily life . pls help me
