negative flip
Yes you do, you also flip the inequality sign if you multiply by a negative # The > and < signs are strictly the "Greater than" and "Less than" signs. The inequality sign is an = with a / stroke through it. If you divide an inequality by -1 it remains an inequality.
You can add, subtract, multiply, or divide both sides of the equation or inequality by the same number. Don't multiply or divide by zero. In the case of an inequality, if you multiply or divide by a negative number, the sign of the inequality must be reversed. E.g., if you multiply both sides by -2, a "less-than" sign should be replaced by a "greater-than" sign.
The sign changes if you multiply/divide by a negative number. It stays the same if you add/subtract by a negative number.
Treat it like a normal equation. Except if you divide/multiply by a negative number you reverse the inequality. That's basically it.
The usual case is when you multiply or divide an inequality by a negative number.
negative flip
The inequality sign must be flipped.
When solving an inequality, you must revers the inequality sign when you multiply (or divide) both sides by a negative number.
Change the direction of the inequality.
Only when you multiply or divide by a negative number
Yes you do, you also flip the inequality sign if you multiply by a negative # The > and < signs are strictly the "Greater than" and "Less than" signs. The inequality sign is an = with a / stroke through it. If you divide an inequality by -1 it remains an inequality.
The inequality sign changes direction. So 2<3 Multiply by -2 and you get -4>-6 (similarly with division).
You can add, subtract, multiply, or divide both sides of the equation or inequality by the same number. Don't multiply or divide by zero. In the case of an inequality, if you multiply or divide by a negative number, the sign of the inequality must be reversed. E.g., if you multiply both sides by -2, a "less-than" sign should be replaced by a "greater-than" sign.
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
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.
The sign changes if you multiply/divide by a negative number. It stays the same if you add/subtract by a negative number.
