commutative property

it is the associative property

Yes because if 1+0=1 than 0 plus b equals b

A=0 b=0 c=0

Commutative

No.

The commutative property of addition. a + b = b + a

no, it's the commutative property of addition.

x = -c/(a+b), provided a+b is not 0

This is the associative law for addition: If a, b, c are any numbers then: a + (b + c) = (a + b) + c

That factors to (a + 1)(a + b) a = -1, -b b = -a

Because there is no way to define the divisors, the equations cannot be evaluated.

Addition is commutative. That is, a + b = b + a for all a, b

Either a=0 or b=0

Symmetry, which states that if A = B then B = A Put A = 4 and B = x + y

It is called the commutative property, a + b = b + a

No, 5 = 5 + 0 is an example of the Zero Identity Property of Addition. The Symmetric property is a + b = b + a, so you're basically just reversing two terms and saying they're equal to each other.

Real numbers are commutative under addition (and subtraction) so a + b - a = a - a + b The set of Real numbers includes an additive identity, 0, such that a - a = 0 so a - a + b = 0 + b The additive identity also has the property that 0 + b = b [= b + 0] so 0 + b = b

a = 0, b = 0.

x + y + z = 0 x = a - b, y = b - c, z = c - a, therefore a - b + b - c + c - a = ? a - a + b - b + c - c = 0

they are additive inverses

A*(B-B) = A*0 = 0 Expanding the left hand side, using the distributive property, A*B + A*(-B) = 0 That is, A*B and A*(-B) are additive inverses. Next, (A-A)*(-B) = 0*(-B) = 0 Expanding, A*(-B) + (-A)*(-B) = 0 Therefore A*(-B) and (-A)*(-B) are additive inverses But, from above, the additive inverse of -A*B is A*B Therefore (-A)*(-B) = A*B It is not known when this was proven.

a + c - b = 3 + 2 - 5 = 5 - 5 = 0
