# Does the inequality sign change when subtracting?

## Does the inequality sign change when subtracting?

Rule 1. Adding or subtracting the same quantity from both sides of an inequality leaves the inequality symbol unchanged. Multiplying or dividing both sides by a negative number reverses the inequality. This means < changes to >, and vice versa.

## Why do you not have to reverse the inequality symbol when adding or subtracting to each side?

Subtracting the same number from each side of an inequality does not change the direction of the inequality symbol. If a < b and if c is a positive number, then a · c < b · c. Multiplying each side of an inequality by a positive number does not change the direction of the inequality symbol.

## Do you flip the inequality sign when you divide by a positive?

Dividing each side of an inequality by a positive number does not change the direction of the inequality symbol. If a < b and if c is a negative number, then a · c > b · c. Multiplying each side of an inequality by a negative number reverses the direction of the inequality symbol.

First of all, we can add inequalities with the same direction. In other words, with the inequalities pointing in the same direction. So if a is greater than b and c is greater than d, then we can just add them together. For example, 5 is greater than 2 and 11 is greater than 8, those are two true inequalities.
