Question

What is the effect of multiplying both sides of an inequality by a negative number? Explain and give an example.

Answer 1

Answer: You would swap the ineqaulity

Explanation:

Multiplying or dividing both sides by a negative number reverses the inequality. This means < changes to >, and vice versa. For example, given that 5 < 8 we can multiply both sides by 6 to obtain 30 < 48 which is still true.
