The Abelian property or commutative property.
The property you described, where x + y = y + x, is called commutativity. In the case of addition, it is called the commutative property of addition.
symmetric property of equality
Identity
The zero property because it has a zero.
Symmetric Property of Addition
Yes. According to the commutative property of addition: x + 3 = 3 + x
The Abelian property or commutative property.
If: x+3 = 3+7 Then: x = 7
The property you described, where x + y = y + x, is called commutativity. In the case of addition, it is called the commutative property of addition.
Well, if x+3=5 and 2+3=5, I'm guessing x should equal 2
symmetric property
symmetric property of equality
The Commutative Property of Addition. It also works for multiplication: 3 times 2 is equal to 2 times 3.
Identity
Commutative property of addition of numbers.
The zero property because it has a zero.
