I used it as my first job before college when i was working in an office environment! This is one way that you can get your feet wet if there's zero risk involved with learning through practice at work (it gets very boring after awhile). Nothing really comes along until about 3rd or 4th grade where they start teaching more advanced math concepts such us logarithms etc; however these are things which will be covered eventually regardless so don't worry too much here just have fun while practicing some basic skills like calculating interest/principle payments due dates from simple loan applications!!
