u only reverse the sign when u multiply or divide by a NEGATIVE number...otherwise u don't change the direction
What is the comparison symbol of 4 1?

What is the math symbol for is at most?

Who invented strict inequality symbol?
my dad
How does an inequality symbol act differently than an equal symbol?
An inequality is not a reflexive relationship.
What happens to the inequality symbol when you subtract a negative number?
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.
How do you divide by a negative in an inequality?
You divide as normal BUT you change the direction of the inequality symbol, so that < becomes > and conversely.
When do you change the direction of an inequality symbol?
When a side is multiplied or divided by a negative number.
When solving an inequality when is it necessary to change the direction of the inequality symbol?
When the two sides of the inequality are multiplied or divided by a negative number or term or expression.

What is the effect of multiplying both sides of an inequality by a negative number?
It changes the direction of the inequality.
When you multiply both sides of any inequality by a negative number you need to do what to the inequality symbol?
You need to change it to the opposite direction; e.g 5 > 1; multiply both sides by -2 it becomes -10 < -2
Is it true When dividing by a negative number the direction of the inequality symbol MUST be reversed?
Yes, it is true.
How do you put greater than symbol on the calculator?
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.
What is the comparison symbol of 4 1?
The inequality symbol.
If you multiply an inequality by a negative number when should you reverse the inequality symbol?
Always.
Do you swap the inequality symbol when its on the right?
No you do not.
