Question

Add the following expressions using column method:

$-15a-6b,-3a+5b,16a-10b$

Answer 1

Adding the given expressions:

Here each expression is written in a separate row such that the like terms are arranged one below the other. Then the addition of terms is carried out:

$$\begin{gathered} -15a-6b \\ -3a+5b \\ 16a-10b \\ \overline{-2a-11b} \end{gathered}$$

Hence, $-15a-6b,-3a+5b,16a-10b$ sums to $-2a-11b$
