Inequality Operations and Their Effects

The video tutorial covers lesson 12 on inequality symbols. The teacher apologizes for a previous recording error and proceeds to explain how to preserve inequality symbols when adding or subtracting numbers. The lesson also covers reversing inequality symbols when multiplying by negative numbers. Various station activities are detailed to practice these concepts. The session concludes with a reminder to complete classwork and an exit ticket.

What does it mean to preserve an inequality symbol?

• To keep the inequality symbol the same

• To multiply by a negative number

• To add a number to both sides

• To change the direction of the inequality

When you add the same number to both sides of an inequality, what happens to the inequality symbol?

• It reverses

• It stays the same

• It becomes an equality

• It disappears

If you subtract 3 from both sides of the inequality 5 > 2, what is the resulting inequality?

• 2 > -1

• 5 > 2

• 5 < 2

• 2 < -1

What happens to the inequality symbol when you multiply both sides by a negative number?

• It stays the same

• It becomes an equality

• It disappears

• It reverses

If you multiply both sides of the inequality -3 < 4 by -1, what is the new inequality?

• 3 < -4

• -3 > 4

• 3 > -4

• -3 < 4

When multiplying both sides of an inequality by a positive number, what happens to the inequality symbol?

• It becomes an equality

• It reverses

• It stays the same

• It disappears

If you multiply both sides of the inequality -2 > -4 by 0.5, what is the resulting inequality?

• -1 < -2

• -1 > -2

• -2 > -4

• -2 < -4

What is the effect of dividing both sides of an inequality by a positive number?

• The inequality symbol disappears

• The inequality symbol stays the same

• The inequality becomes an equality

• The inequality symbol reverses

If you multiply both sides of the inequality 3 > -2 by -2, what is the new inequality?

• 6 > -4

• 6 < -4

• -6 < 4

• -6 > 4

What happens to the inequality symbol when both sides are multiplied by a negative number?

• It stays the same

• It reverses

• It disappears

• It becomes an equality
