📖 Let Us Begin!
Arjun is standing in a line. Ravi stands just before him and Meena stands just after him. In the same way, numbers also stand in a line! Every number has a number just before it and a number just after it. And between two numbers, there is always one number hiding. Let us find them!
Just Before
The number just before is always 1 less than the given number.
Example: Just before 15 is 14. (15 - 1 = 14)
Just before 30 is 29. Just before 50 is 49.
Just After
The number just after is always 1 more than the given number.
Example: Just after 22 is 23. (22 + 1 = 23)
Just after 39 is 40. Just after 47 is 48.
Between
The number between two numbers comes in the middle. It is 1 more than the smaller number and 1 less than the bigger number.
Example: Between 18 and 20 is 19.
Between 34 and 36 is 35. Between 41 and 43 is 42.
Think of it like a sandwich: the number in the middle is the filling!
