To understand inequalities, first learn to compare numbers. Start by looking at the two numbers you have. For instance, consider 28 and 30. Which of these is larger?

You’ll notice that if you count from 28 upwards, you will still reach 30, suggesting that 30 is larger than 28. This process helps in determining the relationship between numbers. Use visual aids like number lines to make understanding easier. For example, the number that appears further to the right on the number line is always the larger one. Regular practice will make comparing numbers second nature.

> (greater than)

Use the inequality symbol '<' when the first number is smaller, and '>' when the first number is larger. For instance, in the example 28 and 30, since 28 is smaller than 30, we use the symbol '<'.


So, the inequality is written: 28 < 30. Similarly, if a number is greater than another, you would use the '>' symbol. This specific and clear notation aids in avoiding confusion in mathematical expressions and solutions.

Basic math concepts like addition, subtraction, multiplication, and division form the foundation of understanding inequalities. Let's break down why this is important:

- **Addition**: Adding the same number to both sides of an inequality doesn't change the relationship. If 28 < 30, then 28 + 3 < 30 + 3.
- **Subtraction**: Similarly, subtracting the same number from both sides doesn't affect the inequality. If 28 < 30, then 28 - 2 < 30 - 2.
- **Multiplication and Division**: These operations can get trickier. When multiplying or dividing both sides by a positive number, the inequality remains the same. If 28 < 30, then 28 * 2 < 30 * 2. However, if multiplying or dividing by a negative number, the inequality symbol flips. For example, if multiplying by -1: 28 (-1) > 30 (-1), so -28 > -30.

Keep practicing these operations with inequalities to grasp how basic math principles apply. It will make solving and understanding inequalities simpler and more intuitive.
