Question

Match the items in column-I with corresponding items in column-II.

Column 1	Column 2
$22+77=77+22$	Commutativity under multiplication
$2+(3+6)=(2+3)+6$	Associativity under multiplication
$5+0=5=0+5$	Commutativity under addition
$12\times 99=99\times 12$	Associativity under addition
$11\times (2\times 7)=(11\times 2)\times 7$	Identity under addition

Answer 1

Step I - Explanation for A -

In commutative under addition, the addition of two whole numbers will remain same if their numbers are interchanged.

$a+b=b+a$.

Step II - Explanation for B -

In associative under addition, the addition of three or more than three will remain same. It is not necessary to add them in the order they are given.

$a+(b+c)=(a+b)+c$

Step III - Explanation for C -

In identity under addition, If 0 is added to any whole number, the sum is number itself.

$a+0=a=0+a$

Step IV - Explanation for D -

In commutativity under multiplication, the product of two whole numbers will remain same whatever be the order of multiplication.

$a\times b=b\times c$

Step V - Explanation for E -

In associativity under multiplication, the product of three whole numbers will remain same even if their arrangements are changed.
