Math is not foreign to life's experiences; rather, it's a beautiful way of understanding our selves and our world. Example, Take the mathematical concept of functions e.g fx - read f of x -. While the Idea of saying f is a function of x seems out of this world, nobody would have any problem understanding that if you buy granola bars, you spend money. If you buy more granola bars, then you spend more money. To model this relationship mathematically, we will say that the money spent -f(x)- is a function i.e. depends on the number of granola bars bought-x-. Now, if each bar cost $2, then 2 bars will cost $4. This relationship can be modelled as f(x)=2x. When x=5 then f(5)=10 and so on.
