Yes, Jake is correct. When you add 0 to any number, the value remains unchanged. This concept is known as the "additive identity property" in mathematics.
To understand why adding 0 does not change a number, it helps to review the properties of addition. One important property is the identity property, which states that for any number, adding zero to it will always result in the same number. In other words, 0 is the identity element for addition.
To demonstrate this, let's take an example using a specific number, say 5.
If we add 0 to 5, the calculation would look like this: 5 + 0 = 5. And as we can see, the result is still 5, which verifies that adding 0 does not change the initial value.
This principle can be applied to any number. For instance, if we add 0 to -10, the result will still be -10: -10 + 0 = -10.
Therefore, Jake's statement that adding 0 does not change a number is correct and aligns with the properties of addition in mathematics.
