Question

When you multiply or divide each side of an inequality by the same negative number, you must reverse the direction of the inequality symbol. Explain why?

Answer 1

Give the explanation

• When you multiply or divide each side of an inequality by the same negative number, you must reverse the direction of the inequality symbol.
• It is because, by multiplying or dividing with the negative number the sign of the numbers changed.
• So, to satisfy the condition of inequality, direction of inequality should also be reversed.
