Solve inequality calculator

Solve inequality calculator : Before using an inequality calculator, you must know what it actually is. If we try to explain in simple words, inequality means it is not equal. In writing, we represent equal as (=). Similarly, if something is not equal, we represent it with this symbol (≠).

Now let’s try to understand further: under inequality, (>) means it is greater. Likewise, (<) means it is smaller. To understand with an example, 10 > 5 (10 is greater than 5), and similarly, 3 < 8 (3 is smaller than 8). By now, you must have understood this concept, and you also know what inequality calculation is.

Now let’s try to understand inequality in a better way. Let’s try it with (X). Suppose x > 5 means: x can be any number that is greater than 5, like 6, 7, 8, 9, 10, and so on. By this point, you must have understood the difference.

To learn and understand inequality in an easier way, I will tell you a trick: the side whose mouth is open is the bigger one. For example, 7 > 3 (the mouth opens towards 7, so 7 is bigger). One more thing, its mouth always opens only towards the bigger number.

7 > 3 (mouth opens towards 7, so 7 is bigger)
3 < 7 (mouth opens towards 7 – correct!)

Remember the trick given below:

The bigger number always comes near >
The smaller number always comes near <

Now let’s learn the formula and rules of inequality

Solve inequality calculator: Below, we are going to tell you some important formulas and rules of inequality: actually, there are 4 main ones:

Addition and Subtraction Rule: When you add or subtract the same number on both sides of an inequality, the inequality sign remains the same. This rule always works.

Multiplication and Division by Positive Numbers: When you multiply or divide both sides of an inequality by a positive number, the inequality sign stays the same. This rule is very simple with positive numbers.

Multiplication and Division by Negative Numbers: This is the most important rule! When you multiply or divide both sides of an inequality by a negative number, you have to flip the inequality sign. That means > becomes <, and < becomes >.

Why does it flip? – Because multiplying by a negative number reverses the positions on the number line. What was bigger before becomes smaller.
