Question

For each expression, rewrite the expression to illustrate addition only. Evaluate eachexpression, if possible.A.-6 + 15 - 18 - 2B.2m – 8m - 9 - 1/2p

Answer 1

A.

`\begin{gathered} -6+15-18-2 \\ to\text{ illustrate addition only, the expression will be written as } \\ (-6)+15+(-18)+(-2) \\ \end{gathered}`

To evaluate the expression further, we will have:

`\begin{gathered} (-6)+15+(-18)+(-2) \\ -6+15-18-2 \\ =-11 \end{gathered}`

B.

`\begin{gathered} 2m-8m-9-(1)/(2)p \\ to\text{ illustrate addition only, the expression will be written as } \\ (2m)+(-8m)+(-9)+(-(1)/(9)p) \end{gathered}`

To evaluate the expression further, we will have

`\begin{gathered} (2m)+(-8m)+(-9)+(-(1)/(9)p) \\ 2m-8m-9-(1)/(2)p \\ -6m-9-(1)/(2)p \end{gathered}`
