If two sides of an inequality are multiplied (or divided) by a negative number, you have to invert the sign. For example, a "less-than" sign becomes a "greater-than" sign.
negative flip
No. Only when you divide by a negative.
The sign changes if you multiply/divide by a negative number. It stays the same if you add/subtract by a negative number.
The relation = , is less than, is greater than inequality sign
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.
negative flip
Flip it around
When you divide both sides of an inequality by a negative number, the inequality sign flips.
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.
When you divide both sides by a negative value
The direction of the inequality remains unchanged. The direction changes when you divide or multiply both sides by a negative number. It also changes if both sides are raised to a negative exponent.
No. Only when you divide by a negative.
The sign changes if you multiply/divide by a negative number. It stays the same if you add/subtract by a negative number.
The relation = , is less than, is greater than inequality sign
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 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.
