Inequalities

Is a relation that makes a non-equal comparison between two mathematical expressions using comparators as >, <, ≤, and ≥, among others.

Some usual operations performed in equations cannot be done in the same way in inequalities, especially multiplying or dividing by negative numbers. When we need to multiply or divide by a negative number, the inequality sign must be flipped.

Let's start off with the inequality

4>-3

a) Add 3 to each side:

4+3>-3+3

7>0

b) Subtract 2 from each side:

4-2>-3-2

2>-5

c) Multiply each side by 2:

2*(4)>2*(-3)

8>-6

d) Multiply each side by -3. We must flip the sign:

-3(4)<(-3)(-3)

-12<9
