In addition, the identity property means that any number plus zero is that number. For example 2+0 =2, -25 + 0 = -25, and so on.
In multiplication, the identity property means that any number or variable times one equals that number. For example 5 x 1 = 5, -12 x 1 = -12, y x 1 = y, 4n x 1 = 4n, and so on.

No, the math term ratio doesn't mean multiply.
having the property that one term operating on a second is equal to the second operating on the first, as a × b = b × a.
This is the Identity Property so it is the the Additive Identity and Multiplicative Identity.
