Suppose x is any number.
Then the inverse property says that there is a number, which we write as "-x" such that x + (-x) = 0 = (-x) + x
Suppose x = 4.7 then -x = -4.7 and their sum is zero.
Or suppose x = -sqrt(3). Then x = +sqrt(3) and again, their sum is zero.

properties of addition with example
Commutative property: For any two numbers a and b, a + b = b + a Associative property: For any three numbers, a b and c, a + (b + c) = a + b + c = (a + b) + c Other properties, such as the existence of an identity and of an inverse depend on the set over which addition is defined. For example, the first two properties mentioned above are true for addition defined on the set of positive integers, N+. But this set does not include the additive identity (zero), nor the inverse of any element in the set. So the second pair of properties are not general but only when defined over specific sets.
If two functions are the inverse of each other, they reverse or undo what the other function does. To give the simplest example, addition and subtraction are inverse functions, so that if you start with 7 and add 3 you get 10, and then if you subtract 3 you are back to 7, which is what you started with, so the subtraction reverses the effect of the addtion (if you subtract the same amount, which in this example was 3).
The zero property in which the answer will not be affected. For example: 15+0=15 The commutative property in which the numbers are changed in order. For example: 5+9+2=2+5+9 Last is the associative property in which only the parenthesis are changed in position. For example: (9+2)+7=9+(2+7)
nope. Multiplication is a form of addition. Division is a form of subtraction.
