In the Windows version of ClarisWorks, some formulas within "( )" don't calculate properly in the spreadsheet environment. For example: The formula   =(-1)^3  should return the value -1, but returns 1 (positive one) instead.  
If the (  ) are removed from the formula,  =-1^3 returns the correct -1 (negative one) value.
In another example, if the formula were  =(2-3)^3,  the answer should be -1, but is still 1 (positive one).  
The (  ) cannot be removed in this instance to product the correct answer .
This only exists with ClarisWorks for Windows.
