Question

Add:
6ax − 2by + 3cz, 6by − 11ax − cz and 10cz − 2ax − 3by

Answer 1

Writing the terms of the given expressions (in the same order) in the form of rows with like terms below each other and adding column-wise, we get:

$$\begin{gathered} \underline{6ax-2by+3cz \\ -11ax+6by-cz \\ -2ax-3by+10cz} \\ -7ax+by+12cz \end{gathered}$$
