Make the Sacred Geometry Pathfinder feat a more viable option! Easily find out how to transform dice rolls 1 - 6 into a needed prime number. The calculator's result string is executed from left to right (that is 6+4/2+2 is 7, not 10). As such, there are some problems that may be solvable with parenthesis that the calculator cannot solve. However, it still works very well as there are few problems that need parenthesis to be solved. Try it out!
