Properties of Whole Numbers:-
When we look into various operations on numbers closely, we notice several
properties of whole numbers. These properties help us to understand the
numbers better. Moreover, they make calculations under certain operations
very simple.
Find 2 × 6;
3 × 3; 4 × 2
using the
number line.
Let each one of you in the class take any two whole numbers and add them.
Is the result always a whole number?
Your additions may be like this:
Try with five other pairs of numbers. Is the sum always a whole number?
Did you find a pair of whole numbers whose sum is not a whole number?
Hence, we say that sum of any two whole numbers is a whole number i.e. the
collection of whole numbers is closed under addition. This property is known
as the closure property for addition of whole numbers.
Are the whole numbers closed under multiplication too? How will you
check it?
Your multiplications may be like this :
The multiplication of two whole numbers is also found to be a whole
number again. We say that the system of whole numbers is closed under
multiplication.
Closure property: Whole numbers are closed under addition and also
under multiplication.
Think, discuss and write:
1. The whole numbers
are not closed under
subtraction. Why?
Your subtractions may
be like this :
Take a few examples of your own and confirm.
Discuss with your friends:
You have a small party at home.
You want to arrange 6 rows of
chairs with 8 chairs in each row
for the visitors. The number of
chairs you will need is 6 × 8. You
find that the room is not wide
enough to accommodate rows of
8 chairs. You decide to have 8 rows of chairs with 6 chairs in each row. How
many chairs do you require now? Will you require more number of chairs?
Is there a commutative property of multiplication?
Multiply numbers 4 and 5 in different orders.
You will observe that 4 × 5 = 5 × 4.
Is it true for the numbers 3 and 6; 5 and 7 also?
You can multiply two whole numbers in any order.
We say multiplication is commutative for whole numbers.
Thus, addition and multiplication are commutative for whole numbers.
