explain closure property?
Closure property under addition:
Integers obey the closure property under addition
for any two integers a and b, a+b is an integer
E.g 3+5=8 , 9+7=16
Closure property under subtraction
Integers are closed under subtraction
For any two integers a and b , a - b is an integer
E.g. 21-(-9) = 30 and 15 - 17 = -2 which are all integers
Closure property under multiplication
Integers are closed under mulltiplication
for every integer a and b , a×b is an integer
E.g. 5×4=20 and -7×9 = -63 which are all integers
Closure property under division
Integers are not closed under division
for every integer a and b a/b might not be an integer
E.g. 9/3 = 3 which is an integer but 14/5 = 2.8 which is not an integer.
