Leave it alone. You cannot make an inequality into an equality by multiplying both sides of the inequation by the same number. If instead of the inequality sign you are using a lesser or greater than sign, however, you will need to reverse it if you multiply both sides by the same negative number, e.g.
10>4.
If you multiply both sides by -2, you need to change the > into a <, so
-20<-8
The inequality sign must be flipped.
You divide the negative number by a positive number for it to stay positive. And you divide the negative number by a negative number for it to become positive.
multiply the numbers together and the sign is positive , as a negative times a negative is a positive
A negative number.
Becuase in the rule of laws of signs, when you multiply or divide a number that is positve by a negative number or a number that is negative by a positive number (same thing), the product/answer will always be a negative number. But when you multiply/divide a positive number by positive or negative by negative, the product/answer will always be positive number E.g: -2 x 2= -4 / 2 x (-2)= -4 -2 -:- 2= -1 / 2 -:- (-2)= -1 E.g: 2 x 2=4 / -2 x (-2)=4 2 -:- 2= 1 / -2 -:- (-2)=1
The usual case is when you multiply or divide an inequality by a negative number.
The inequality sign must be flipped.
negative flip
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.
