Addition works because like all mathmatics as long as you know 1/2 of the equation, answer, and type of equation (addition,subtraction,multiplication, or division) there is only 1 answer.
A product is the answer of a multiplication equation. A sum is the answer of an addition equation.
The summands Also the addends
because you undo the operation in the equation= to undo subtraction you add
To add the same value to all sides of a equation
Addition and subtraction are inverse operations. So you can solve addition by subtracting.

A product is the answer of a multiplication equation. A sum is the answer of an addition equation.
The addition property of equality states that if you add the same number to both sides of an equation, then the sides remain even. This means that the equation remains to be true.
numbers that are combined in addition process
The summands Also the addends
because you undo the operation in the equation= to undo subtraction you add
plus sum add quantity
To add the same value to all sides of a equation
x + 2 = 0
The balanced equation for the addition of water to quicklime, which is calcium oxide (CaO), is: CaO + H2O → Ca(OH)2.
So if the addition property is just that adding something to both sides of an equation makes it stay equal, then this is exactly what it is used for. a = b, so a+ c = b +c
