Learn moreIn the previous class, we learned about natural numbers.
Natural numbers are \(1\), \(2\), \(3\),…. They are also called as positive numbers.
Have you ever heard about negative numbers?
Yes, we heard these numbers in day-to-day life.
Example:
1. The average temperature in the Antarctic Plateau is .
2. Your account balance is \(-100\) rupees.
Negative numbers are \(-1\), \(-2\), \(-3\),…. They come below zero.
Now, let us define integers.
Integers are the set of positive and negative numbers, including zero. Usually, it is written as …, \(-3\), \(-2\), \(-1\), \(0\), \(1\), \(2\), \(3\), ….
Let's see about the sign of integers.
The opposite of every positive number is the same number with a negative sign.
Example:
1. The opposite of \(5\) is \(-5\).
2. The opposite of \(10\) is \(-10\).
3. The opposite of \(-15\) is \(15\).
Important!
The opposite of \(0\) is \(0\). It is because zero is neither a positive nor a negative.
