Question

Which of the following is an example of the associative property of addition?

• A. x + (y+z) = xz + xy
• B. x $\times$ (y + z) = xy + xz
• C. x + (y + z) = x (y + z)
• D. y + (z + x) = (y + z) + x

Answer 1

The correct option is D

y + (z + x) = (y + z) + x

The associative property states that you can add or multiply regardless of how the numbers are grouped. For example, a + (b + c) = (a + b) +c.
Therefore, the fourth option is correct.
