When we compare two numbers, we use the "less than" symbol to show that the first number is smaller than the second number. The "less than" symbol is denoted by "<". For example, if we compare the numbers 3 and 5, we would write it as:

3 < 5

This statement reads as "3 is less than 5".

- Always place the smaller number on the left side of the "less than" symbol and the larger number on the right side.
- When comparing two numbers, if the first number is smaller than the second number, the statement is true. Otherwise, it is false.

1. 2 < 4 - This statement is true because 2 is less than 4.

2. 7 < 3 - This statement is false because 7 is not less than 3.
