Natural numbers are those collections of numbers that can be counted by hand. For example 1, 2, 3, 4,....etc. are natural numbers in which 1 is the smallest number in the collection. 0, negative numbers, decimals and fractions are not considered natural numbers. Whole numbers include 0, natural numbers and positive integers as well except for decimals and fractions. Arithmetic operations can be performed on whole numbers like addition, subtraction, multiplication and division. 0 is the smallest whole number.

**4. How do we add or subtract whole numbers on the number line?**

A number line includes numbers that are placed in equal segments with the starting point being 0. The rest of the numbers continue and extend towards the right (for positive integers) and towards the left (for negative integers). Calculations on the number line are done to compare the predecessors and the successors as well as to perform Mathematical operations like addition, subtraction and multiplication. In addition, students must calculate from the right of the integers in question and to subtract, move towards the left of the number line.
