addition
Is addition of integers commutative?
Yes it is : a + b = b + a for all integers a and b. In fact , if an operation is called addition you can bet that it is commutative. It would be perverse to call an non-commutative operation addition.
Is the set of all negative integers closed for operation of addition?
yes
Is the set of all integers closed under the operation of multiplication?
Yes.
Which operation used to close the set of positive even integers?
1) addition
What are two same integers that would end up with the same answer?
The answer depends on what the operation is.
Is the set of positive integers a commutative group under the operation of addition?
No. It is not a group.
What are the rules on four fundamental operation of integers?
add subtract divide multiplication
What are the two consecutive integers of 224?
There are no consecutive integers that add or multiply to 224. If you meant some other binary operation, you should specify what you meant.
Why is a set of positive integers not a group under the operation of addition?
The set of positive integers does not contain the additive inverses of all but the identity. It is, therefore, not a group.
Which set is closed under the given operation 1 integers under division 2 negative integers under subtraction 3 odd integers under multiplication?
1 No. 2 No. 3 Yes.
