Ms Jones gave the inequality −?? < 5 to the learners and got them find the solution set of the inequality. One of the learners divided both sides of the inequality with -1 and got the solution as ?? > −5. Then, another learner asked why the direction of the inequality sign was changed when both sides of it were divided by -1. What would you tell the learner if you were the teacher in the classroom?

Lucinda and Marco compare 4 and -2. Lucinda claims that 4 is to the right of -2 on the number line, and so 4 > -2. Marco claims that 4 is to the left of -2 on a number line, so 4 -2. Marco is incorrect. On a number line, 4 is not to the left of -2. Lucinda is incorrect. On a number line, 4 is not to the right of -2.
