REGENT EXAMS In the following questions all the student needs to do is to replace the variable by the choices, one by one, until the two sides of the equation are equal -- as instructed in drill-and-kill sessions. No need to know algebra. He/she does not have to worry about sign numbers' operations either (many students' bete noire) : a calculator will take care of that, and make it even irrelevant whether the equation is complexe or not.
