The associative property states that the way in which numbers are grouped does not change their sum: (a + b) + c = a + (b + c).
The associative property states that the order of addition does not change the outcome.
Associative property only applies to multiplication, not addition.
The result is multiplied by the number of addends.
Subtraction involves increasing numbers.
Subtraction involves taking away or decreasing, whereas addition involves combining or increasing numbers.
Subtraction combines numbers like addition.
Subtraction increases as multiplication does.

1 less than the original number
Adding 0 to a natural number results in the same natural number.
1 more than the original number
Yes, as long as the number being subtracted is smaller than the number it is being subtracted from, the result is also a natural number.
No, subtraction always results in non-natural numbers.
Yes, but only for even numbers.
No, subtraction is undefined for natural numbers.
