Negative Numbers
Numbers less than zero, marked with a minus sign (like -1, -5), used to represent opposites of positive values such as debt or temperatures below freezing.
Integers
A bigger collection of numbers that includes whole numbers, positive natural numbers, and negative numbers (..., -3, -2, -1, 0, 1, 2, 3, ...).
Number Line Representation
A straight line with zero in the middle, positive numbers on the right side, and negative numbers on the left side to visualize integer values.
Opposite Numbers
Numbers that are the same distance from zero in opposite directions, such as +5 and -5, where their sum is always zero.
Comparison of Integers
On a number line, any number to the right is always greater than the number to its left, meaning every positive integer is greater than any negative integer.

Frequently Asked Questions
Is zero a positive or negative integer?
Zero is neither a positive nor a negative integer; it is a neutral integer that acts as the dividing line between positive and negative numbers.
Which is greater, -5 or -2?
-2 is greater than -5 because on the number line, -2 lies to the right of -5, and numbers to the right are always larger.
How do we represent a loss of Rs 50 using integers?
A loss is represented by a negative sign, so a loss of Rs 50 is written as -50.
