Question

Write the expression without parentheses- (-10h - 7w)

Answer 1

By distributing the minus sign into the parentheses, we get

`-(-10h)-(-7w)`

By the law of signs for multiplication and division:

we have that

`\begin{gathered} -(-10h)=+10h \\ and \\ -(-7w)=7w \end{gathered}`

So we have

`10h+7w`

So the answer is: 10h+7w
