u only reverse the sign when u multiply or divide by a NEGATIVE number...otherwise u don't change the direction
If both sides of an inequality are multiplied or divided by the same positive number, the direction of the inequality symbol remains the same. For example, if you have ( a < b ) and you multiply both sides by a positive number ( c ), the inequality remains ( ac < bc ). This property holds true for all positive numbers, ensuring the relationship between the two sides is preserved.

The inequality symbol for less than or equal to: ≤

The inequality symbol doesn't change direction in this case.Note that that is the same as adding a positive number.Note also that if you MULTIPLY or DIVIDE by a negative number, then you need to change the direction of the inequality symbol.
You divide as normal BUT you change the direction of the inequality symbol, so that < becomes > and conversely.
When a side is multiplied or divided by a negative number.
When the two sides of the inequality are multiplied or divided by a negative number or term or expression.
You need to change it to the opposite direction; e.g 5 > 1; multiply both sides by -2 it becomes -10 < -2

It changes the direction of the inequality.
Yes, it is true.
Unless it's a fancy graphing calculator, you don't. When solving an inequality, you need to solve it as an equality, remaining mindful of the proper direction of the inequality symbol after each step.

No you do not.
Always.
