Where do you use math in your profession?

One of the most difficult challenges that math teachers face today is motivating their students. This becomes more difficult when faced with the all famous question: "What am I going to use this for?"

Help me with some real world examples of modern day math. Please let me know your profession and what type of math you use to share with our students.


Thank you everyone so much for the contributions! They are great and I wasn't expecting such a turn out. My goal is to gain enough examples and to use them at the start of each lecture. I'm hoping that these examples in the beginning of class will spark the student's interest for the reaming of the lecture and to show that that we really do use math.

There is a difference between having to learn something and wanting to learn something. When we have to learn it we just try to get through it. When we want to learn it, this is when we make breakthroughs. Stimulate the interest in students so that they want to learn math and we increase our probability in someone discovering the next breakthrough.

  • Feb 23 2012: If your going to explain math from a pure mathmathecal view point, yes that's hard
    But look around you math is everywhere every physiques formula is a probable example, who don't know the example of car A and B are racing,
    A has speed x
    B has speed y
    B start ahead of A by distance d
    How long will it take A to pass B
    That's a simple physiques formula, could be used as an example.
    Not only physiques there is biology, chimistry, programing, etc...
    Math is everywhere in anything we use, even the sofa I'm sitting on is built using math
    I can't think of anything not related to math, one way or the other.
    One of math fascinating math implementation is in natural inspired algorithm
    there is a software called netlogo with lots of pre programed examples, a bit hard for kids but can be used by the teacher in a session or two to given students some live solved problems
    The software can be found here
