What is the difference between the zero property of multiplication and the identity property of addition?
Usually, the identity of addition property is defined to be an axiom (which only specifies the existence of zero, not uniqueness), and the zero property of multiplication is a consequence of existence of zero, existence of an additive inverse, distributivity of multiplication over addition and associativity of addition. Proof of 0 * a = 0: 0 * a = (0 + 0) * a [additive identity] 0 * a = 0 * a + 0 * a [distributivity of multiplication over addition] 0 * a + (-(0 * a)) = (0 * a + 0 * a) + (-(0 * a)) [existence of additive inverse] 0 = (0 * a + 0 * a) + (-(0 * a)) [property of additive inverses] 0 = 0 * a + (0 * a + (-(0 * a))) [associativity of addition] 0 = 0 * a + 0 [property of additive inverses] 0 = 0 * a [additive identity] A similar proof works for a * 0 = 0 (with the other distributive law if commutativity of multiplication is not assumed).
What is the difference between additive identity and additive inverse?
The additive inverse is a number subtracted it's self is 0: x + (-x) = 0 The additive identity is a number plus/minus 0 is itself: x +/- 0 = x They're very similar
What is called the multiplicative identity for whole numbers and why is it called this?
The multiplicative identity is the number 1. Why? Because if you multiply (or divide) a number by 1, it remains the same. eg a x 1 = a In a similar manner, the additive identity is 0. If you add (or subtract) 0 from a number, it remains the same eg a + 0 = a.
What is the relationship between the additive property and multiplication?
The additive property refers to the principle that when you add a number to zero, the result is the original number, and that the sum of two numbers is the same regardless of their order (commutative property). In multiplication, a similar principle exists where multiplying a number by one leaves it unchanged, and the product remains the same regardless of the order (commutative property). Both properties highlight fundamental relationships in arithmetic, emphasizing how numbers combine to produce consistent results through different operations. Essentially, they are foundational rules that govern how we manipulate numbers in addition and multiplication.
Is self-esteem similar but different from identity?

How are the identity properties of multiplication and addition similar?
Multiplication is simply a shortcut for repeated addition of the same number.For example, 4 x 2 is the same as 2 + 2 + 2 + 2(two added to itself, four times).
What is the opposite of -(-36)?
The opposite of opposite is same, like or similar. A double negative leads to the original identity of the term. So the answer is same or identical.

Addition of similar fractions?
Similar fractions occurs when the denominator or the bottom numbers are the same. In this case, adding similar fractions requires you to add the numerators; the top numbers together, and to keep the denominator the same. An example would be to add 2/8 and 5/8 equals 7/8.
What is the opposite of 22?
The opposite of opposite is same, like or similar. A double negative leads to the original identity of the term. So the answer is same or identical.
How are the properties of multiplication and addition similar?
Mainly that in both cases, the numbers can be changed, in any order. This is related to the commucative property, as well as the associative property, which apply to both. - Also, in both cases there is a neutral element (0 for addition, 1 for multiplication).
What are the rules of subtracting polynomials?
You subtract a polynomial by adding its additive inverse. For example, subtracting (x - y) is the same as adding (-x + y). Alternately, you can simply subtract similar terms - that is, subtract the coefficients (the numbers) for terms that have the same combination of variables.
