Does anybody know this? Which of the properties of real numbers is illustrated in the following example.
Elenna [48]

The property of real numbers that was illustrated in the above example is known as the: D. inverse property.

<h3>What is the Inverse Property of Real Numbers?</h3>

The inverse property of real numbers states that if you add the opposite of a number together with that number, the result would be zero.

For example, if "a" represents a number, the opposite of the number "a" is -a.

Applying the inverse property of real numbers, it states that: a + (-a) = a - a = 0. Both numbers will cancel each other to give zero.

In the same vein, as shown in the image given above:

6 is a number

The opposite of 6 is -6.

Applying the inverse property of real numbers, we have:

6 + (-6) = 0.

In conclusion, we can state that given the expression, 6 + (-6) = 0, the property of real numbers that was illustrated in the above example is known as the: D. inverse property.
