Question

if A and B are two whole number then how we can prove that closure property over these two whole numbers for addition and multiplication


​

Answer 1

Step-by-step explanation:

addition: a=12,b=15

closure property: if a,b are 2 integers, then a+b is also an integer.

a+b=12+15=27.

therefore, 12+15 is also an integer.

multiplication: a=12,b=15

closure property:if a,b are 2 integers,then a×b is also an integer.

a×b=12×15=180.

therefore,12×15 is also an integer.
