There are infinitely many possible answers:3+4, 2+5, 1+6, 0+7, -1+8, -2+9, ...
3.5+3.5, 3.4+3.6, 3.3+3.7, ....
then use numbers with 2 digits after the decimal place, 3 digits, ... , infinitely many digits.
Next, start again with additions involving 3 numbers, 4, numbers, ...,
-10
the addition property for 6 plus 7 equals 7 plus 6 is the commutative property. This property states that - when two numbers are added, the sum is the same regardless of the order of the addends.
That would be called Addition.
8 and 7 6 and 9 10 and 5
commutative property
15 -7 = 8
That is correct!
5+2 = 7
Zero is the identity under addition.
-10
Commutativity of addition.
