10. Consider the equation below, where a, b, and c are whole numbers. a +b - c= a - c+b (a) Is this statement always true, sometimes true, or never true? Justify your response. (b) Torsten said that this statement cannot always be true because subtraction is not com- mutative. What is the flaw in Torsten's argument? (Be sure you are addressing the flaw in his argument, not in his conclusion.)
