It changes the direction of the inequality.
No. Only flip the inequality when multiplying or dividing by a negative number.
When an inequality is multiplied or divided by a negative number the inequality sign is reversed.Example : -x < 7 ......after multiplying by (say) -2 this becomes 2x > -14
When you multiply both sides by a negative number the inequality must be flipped over. You do not do that when multiplying by a positive number.
Flip. You need to reverse the inequality when multiplying or dividing by a negative. -2x < 10 (-1)*(-2x) < (-1)*10 2x > -10 x > -5
You need to reverse the inequality symbol when multiplying both sides of an inequality by a negative number because you are changing the sign of both sides of the equation. Since inequality, such as "less than", means "to the left of" on the number line (where left is minus and right is plus) then a number that is less than another will be greater than the other if the signs were reversed. Example: 3 is less than 4, but -3 is greater than -4.
No. Only flip the inequality when multiplying or dividing by a negative number.
We flip the inequality symbol when multiplying or dividing by a negative number because it preserves the logical relationship between the quantities involved. For example, if ( a < b ) and we multiply both sides by a negative number, the direction of their relationship changes; thus, ( -a > -b ). This is due to the nature of the number line, where multiplying or dividing by a negative number reverses the order of the numbers. Therefore, flipping the symbol ensures that the inequality remains true.

Because your multiping the inverse to both sides
Yes, when you divide or multiply an inequality by a negative number, you must reverse the inequality sign. For example, if ( a < b ) and you multiply both sides by a negative number ( -c ), the inequality becomes ( -ac > -bc ). This change is necessary to maintain the truth of the inequality.
When you multiply both sides by a negative number the inequality must be flipped over. You do not do that when multiplying by a positive number.
The inequality sign flips when both sides of an inequality are multiplied or divided by a negative number because the direction of the relationship between the two values reverses. For example, if ( a < b ) and we multiply both sides by -1, the inequality becomes ( -a > -b ) since multiplying by a negative number changes the order of the values. This does not happen with equations because equations represent equality; multiplying or dividing both sides by a negative number does not change their equality.
When you multiply both sides of an inequality by a positive number, the direction of the inequality remains unchanged. However, if you multiply both sides by a negative number, the direction of the inequality must be reversed. This is crucial to maintain the truth of the inequality. Always be mindful of the sign of the number you are multiplying by.

You do not reverse the inequality symbol when multiplying or dividing both sides of an inequality by a positive number. However, if you multiply or divide by a negative number, you must reverse the inequality symbol. This rule ensures that the direction of the inequality remains true after the operation.
