INTRODUCTION: When this program run, a formula will be asked to user.
              During this step, any user must know those items:

              o Unknown character must be 'X' only
              o The X can be placed in the both side of the formula
              o Describe each operations separetely: such as 7 * X,
                but not 7X
              o Type '.' instead of ',' (14.6 is acceptable, but not 14,6)
              o Each side of formula allows to 46 operations!
              o The formula will be given allows to 94 operands.
              o P character can be used as Pi number (3.142857...)
              o It does not check incorrect formulation, such as  x = 2 * x
              o This version does not contain PARANTHESIS, LOGIC,
                EXPONENTIAL and TRIGONOMETRIC functions.
              o It may not give alert for second power of X, such as
                x*x=9 or x*x*x=27 (This is most reason of wrong result)

EXAMPLES    :
                7*x = 14-23+10+3+5+5      '   x => 2
            2/x+1/x = 45*5/4.5            '   x => 0.06
       13*x/p+24.09 = 0.65*p-x/0.1        '   x => -1.559605
  2/x+12*3.4+2.04/x = 0.45*5/4.5          '   x => -0.1002481
x+4+x+x+x+2-4*x-5/6 = x*6+12-7*x*4-5      '   x => 5.166661
