What best described the number sentence 8 + 0 = 8 is the identity property of addition.
According to the identity property of additions, the sum of 0 and any number is that number.
In mathematical addition, identity has different meanings. Identity in math primarily means the number that when added to another number would give the same number. Mostly added identity is zero (0).
This also explains the identity property of additions which state that whenever an individual add zero to any number, it will always be equal to the number added to it.
There are some vocabulary that are related to additions. These vocabulary are "addends" and "sum". When two or more numbers are added together, it is called addends and a sum is what you get when two or more addends are added together.
In a case that you add the numbers 8 + 0, the sum of this is 8. The rule says addend 8 didn’t have to change its identity when it is added with 0. But we will get a different sum if we add another number different from 0 to 8.
These are examples of identity property of additions.
