Question

examples closure,commutativeand associative

Answer 1

Commutative property : It is generally used for only addition and multiplication.
Example :
Addition-
2+3=5
3+2=5
So, the answer will be the same even if you change the position of the numbers.
Multiplication -
2×3=6
3×2=6
The answer will be the same even if you change the position of the numbers.
Subtraction -
5-4=1
4-5= - 1
The answers are not the same.
Division -
8/4=2
4/8=0.5
The answers are not same.


Closure property: If you add or multiply real numbers the answer is also real. This is also used for addition and multiplication.
Example :
Addition -
5+4=9
All three 4, 5 and 9 are real numbers.
Multiplication -
2×5=10
All three 2, 5 and 10 are real numbers.

Associative property : It means we can add or multiply however the numbers are grouped.
Example :
Addition -
(2+8)+5=15
2+(8+5)=15
Both answers will be same.
Multiplication -
(2×2)×5=20
2×(2×5)=20
Both answers will be same.

Hope it helps you!!
PLEASE MARK THE ANSWER AS BRAINLIEST!! :)

Answer 2

firstly, please tell me which property do you want of addition , substraction, multiplication,division
still,
closure property
if we add a+b the answer would always be an integer
example: 13+9=22(integer)
(-13)+(-9)=-22(integer)
commutative property
a+b=b+a
example:2+4=6 also 4+2=6 so, 4+2=2+4
associative property
a+(b+c)=(a+b)+c
example: 2+(3+4)=(2+3)+4
hope it helps
