Simplifying 27a+(48a)+27a-27a + (-48a) + 27a

To simplify the algebraic expression 27a+(48a)+27a-27a + (-48a) + 27a, recognize that the first and third terms are opposites. Use the commutative property of addition to rearrange the terms so the opposites are next to each other: 27a+27a+(48a)-27a + 27a + (-48a). Adding the opposites yields 00, simplifying the expression to 0+(48a)0 + (-48a). Applying the additive identity property gives the final result of 48a-48a.
