Mathematica is a computational software program used in many scientific, engineering, mathematical and computing fields, based on symbolic mathematics. For the students of mid-level or lower-level of economy it is too hard to buy this software. So for them they need to crack it for getting licence and serial key to use.
Variables are very important in almost every cases. Normally we use local variables but it is sometimes necessary to use global variables. We can not skip that matter with local variables. One of such kind of a problem is finding the sum of integers of any number. I have tried many times to use local variable here but failed. If you can please suggest me. But the program code is given here which I have written.
