Question:Please help me.
Commutative
Associative
Distributive
Multiplicative property of Zero
Additive
Identity
Thank you for your help.
Answers:Commutative applies to both addition and multiplication. It is if you reverse the 2 addends or factors, the sum or product will be the same. (i.e. 3 + 5 = 8, 5 + 3 = 8; 7 * 3 = 21, 3 * 7 = 21) Associative property is when you change the grouping placement of an all addition or all multiplication equation, the sum or product is the same. (i.e. 2 + (3 + 7) = (2 + 3) + 7; (5 * 3) * 6 = 5 * (3 * 6)) Distributive property (actually Distributive property of Multiplication over Addition) is "distributing" multiplication over grouped addition (i.e. 4 * (7 + 2) = (4 * 7) + (4 * 2)) Multiplicative property of Zero is when any number multiplied by zero is zero (i.e. 4 * 0 = 0, 8 * 0 = 0) Identity property of Addition is when any number is added to 0, the answer is the number. (i.e. 3 + 0 = 3, 42 + 0 = 42, 69 + 0 = 69, 89345679584039 + 0 = 89345679584039) Also note that 0 is the "additive identity". Identity property of Multiplication is when any number is multiplied by 1, the answer is the number. (i.e. 4 * 1 = 4, 42 * 1 = 42, 69 * 1 = 69, 6756975765 * 1 = 6756975765) Note that 1 is the "multiplicative identity",

Question:Can you guys help me with the properties like the communication property of multiplication and addition, and the distributive, and the associative and all of those. I need to know like the definition and an example or just something that explains it to me! Thanks guys! :)
Answers:Properties of Addition : Commutative Property : The Commutative Property of Addition States that changing the order of the addends in addition does not change the sum. a + b = b + a Ex: 7 + (8) = (8) + 7 2 + (5) = (5) + (2) 9 + 4 = 4 + 9 Associative Property : The Associative Property of Addition States that the way the addends are grouped in a sum does not affect the sum. (a + b) + c = a + (b + c) Ex: (3 + 11) + 9 = 3 + (11 + 9) [2 + (2)] + 4 = 2 + (2 + 4) (4 + 8) 6 = 4 + (8 6) The Identity Property : The Identity Property of Addition States that the number 0 is the identity element for addition in the set of whole numbers because adding 0 to any whole number does not change the whole number. a + 0 = a. Ex: 0 + 7 = 7 15 + 0 = 15 11 + 0 = 11 AdditiveInverse Property : The AdditiveInverse Property States that the sum of a number and its opposite is 0. The number opposite the given number is called the additive inverse. Ex: 12 + (12) = 0 (32) + 32 = 0 55 + (55) = 0 Properties of Multiplication : Commutative Property : The order in which two numbers are multiplied doesn t change the product. a b = b a Ex: 3 2 = 2 3 Associative Property : The way you group three numbers when multiplying doesn t change the product a (b c) = (a b) c EX: 3 (2 5) = (3 2) 5 Identity Property : The product of 1 and a number is the number. 1 a = a Ex: 1 7 = 7 Property of zero : The product of a number and zero is zero. 0 a = 0 Ex: 0 9 = 0 Property of Opposites : The product of a number and 1 is the opposite of the number. (1) a = a Ex: (1)(3) = 3

(a + b) + c = a + (b + c) Ex: (3 + 11) + 9 = 3 + (11 + 9) [2 + (2)] + 4 = 2 + (2 + 4) (4 + 8) 6 = 4 + (8 6) The Identity Property : The Identity Property of Addition States that the number 0 is the identity element for addition in the set of whole numbers because adding 0 to any whole number does not change the whole number. a + 0 = a.

(1) a = a Ex: (1)(3) = 3
Question:its currently 7:15 and I have tons of homework. I just thought Id quickly ask you guys for these definitons because I cant spend to long searching online because I have to go to bed early cuz I wake up at 3:00 am ( cuz I dont have car to get to school,I bike 8 miles every day to school) Im really sick of getting 4 hours of sleep, can sumone just help out a little? I need these definitons (dont have to answer them all, I dont expect you to waste your time on me)
a) Hypothesis 
b) Dependent variable 
c) Independent variable 
d) Control 
e) Mass 
f) Volume 
g) Density 
h) Miscible 
i) Immiscible 
j) Density Column 
2) Measure mass and volume of liquids and solids using the correct units. (Write down how you measure the mass and volume.)
3) Calculate density using the correct units. (Write down the equation for density.)
4) Name at least 10 properties of matter.
Im trying to get this done (and study it), plus a resume, 3 math pages, + 2 chaps. of a book

Question:If 2 is a true prime number, why does it have to be excluded from 99.99% of the rules that qualify prime numbers?
Answers:99.99% is a monumental exaggeration. Yeah, it's excluded from a lot of theorems, but it shows up in a lot of other theorems. The reason it's left out so often is because so many theorems rely on primes being odd, which is a property 2 doesn't have. This happens a lot in higher math. You define some general concept, then most of the stuff you prove seems to use a more specific version of that concept. In abstract algebra, I was always bothered by the fact that rings were not required to be commutative, but almost every proof we did with them had us assume that they were.
