Extend the number line towards the left of 0. Mark points to the left of 0 leaving the same gap between those points as the gap marked on the number line initially and named those points as -1, -2, -3, …. STEP 01 STEP 02 STEP 02
- 5. The whole numbers leftto the 0 are called Negative Numbers. It is denoted by -1. The sign “-” is called The Negative Sign. The whole numbers to the right of zero are called Positive Numbers. The number Zero is neither positive nor negative. The Positive integers, the Negative integers and Zero, all taken together are called the Integers.
- 6. <Comparison of integers> Thesymbols “>” and “<“ are called Inequality Signs. Larger integer > Smaller integer Smaller integer < Larger integer > Five is greater than two < Two is less than five
