What is the fundamental operation of integers?
Parenthesis Exponent Multiplication Division Addition Subtraction PEMDAS ( the multiplication and division is based on which of them comes FIRST )
What property links multiplication and addition?
The set of integers is closed with respect to multiplication and with respect to addition.
Which operations on integers are commutative?
Addition and multiplication are operations on integers that are commutative.
What operations are closed for integers?
Addition, subtraction and multiplication.
What is the integer rule for combining integers with different signs?
The answer depends on which binary operation you mean when you say "combining". Addition, subtraction, multiplication, division, exponentiation, etc.
Is the set of all integers closed under the operation of multiplication?
Yes.
Is the set of even integers closed under addition and multiplication?
Yes.
How does multiplication of integers compared to addition or subtraction of integers?
Multiplication is the same as repeated addition. For example 12 * 3 = 12 + 12 + 12 12 * 4 = 12 + 12 + 12 + 12 and so on.
Which of the basic rules of arithmetic are true when you restrict the number system to the positive integers?
Closure with respect to addition and multiplication. Cummutative, Associative properties of addition and of multiplication. Distributive property of multiplication over addition.
What are the rules on four fundamental operation of integers?
add subtract divide multiplication
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.
What does it mean if an integer is closed?
You don't say that "an integer is closed". It is the SET of integers which is closed UNDER A SPECIFIC OPERATION. For example, the SET of integers is closed under the operations of addition and multiplication. That means that an addition of two members of the set (two integers in this case) will again give you a member of the set (an integer in this case).
