To multiply negative integers first invision that all signs (positive and negative alike) are gone. Then multiply as you normally would (like 5 x 3 = 15). Then worry about the sign: positive x positive = positive positive x negative = negative negative x positive = negative negative x negative = positive For example, do calculate (-5) x (-3), first invision the signs are gone (5 x 3 = 15). Now worry about the signs (negative x negative = positive). So the answer is +15 (or simply 15). Another, slightly more complicated example: (-4) x (8) ignore the signs: 4 x 8 = 32. Worry about the signs: negative x positive = negative So the answer is -32.

How is dividing integers similar to multiplying integers with the resulting sign?
The rules for the sign (positive or negative) of the result of a multiplication is the same as division. For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
Is the answer to adding two negative integers a positive or negative?
When you add two negative integers, the answer is still negative.
What is the answer of negative integers greater than 5?
There are no negative integers greater than five.
Does the commutative property of addition apply when you add to negative integers?
Yes. The commutative property of addition (as well as the commutative property of multiplication) applies to all real numbers, and even to complex numbers. As an example (for integers): 5 + (-3) = (-3) + 5
Is the set of even integers closed under multiplication?
Yes
Are negative integers closed under multiplication?
No.
Is the set of negative integers closed under multiplication real numbers?
No, it is not.

For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
What is the rules for multiplication integers?
When multiplying integers, multiplying by the same sign will always produce a positive integer. Such as a negative times a negative equals a positive. If the signs are different then the product will be a negative.
When you add 2 negative integers is the sum positive or negative?
Negative. -2 + -3 = -5 You might be confused with multiplication, where the product is positive
What is the set of whole numbers closed by?
If you mean the set of non-negative integers ("whole numbers" is a bit ambiguous in this sense), it is closed under addition and multiplication. If you mean "integers", the set is closed under addition, subtraction, multiplication.
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.
What is the product of two integers with unlike sign?
The product (meaning multiplication) will be a negative integer. E.g. 2 * -2 = -4
How are multiplying integers and dividing integers same?
following multiplication integer rules and division rules, you should get: "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)" a division problem is a multiplication problem in disguise
Which operations on integers are commutative?
Addition and multiplication are operations on integers that are commutative.
Are all none negative integers are negative integers?
An integer is either positive (non-negative), or negative, or zero. There are no negative non-negative integers.
What are non positive integers?
Non-positive integers are zero and the negative integers.
