The inequality sign changes direction.
So 2<3
Multiply by -2 and you get -4>-6 (similarly with division).
The usual case is when you multiply or divide an inequality by 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.
When solving an inequality, you must revers the inequality sign when you multiply (or divide) both sides by a negative number.
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.
Only when what you're multiplying by/dividing by is negative.

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 sign must be flipped.
negative flip
yes ... and so?
the answer becomes negative
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.

Change the direction of the inequality.
