Sentence Fragments

                      As used in this program, sentence fragments are phrases that cannot be solved, but can be translated into algebraic expressions.
                      For example, the phrase, a number added to 4, translates into the algebraic expression N + 4. 
                      When using the Solver to translate sentence fragments, check the Sentence Fragment check box on the Input Panel. Failure to check this box for sentence fragments will result in an unsolved problem.
                      By itself, the expression has no solution, but when the expression is completed to form a sentence, it can form an equation.
                      For example, the sentence, a number added to 4 is equal to 9, translates into the algebraic equation  N + 4 = 9.
