First one:
This is the commutative property of addition, which states that for two addends, the order of addends does not affect the value of the end result.
Second one:
This is the multiplicative identity property. It states that any number, when multiplied by 1, is equal to itself.
Third one:
This is the additive identity property, which states that any number, when added to 0, equals the same number.
Hope this helps!
