Integers

 

 

When we move below zero, we assign negative signs to those numbers on the number line. These numbers are called negative numbers.

For example, if we go 10 km below the sea level, we represent it as –10.

The collection of numbers,  … –3, –2, –1, 0, 1, 2, 3 …, are called integers.

–1, –2, –3 … are called negative integers whereas 1, 2, 3 … are called positive   integers.
