Question 147854
Hi, Hope I can help
.
Simplify the expression -[-(4+3)]
.
You have to work on the inside and work out
.
First we add
.
{{{ -(-(4+3)) }}}
{{{ -(-(7)) }}}
.
We will remove the parentheses, which will make 7 a negative
.
{{{ -(-7) }}}
.
Now we will remove the next parentheses, it will make it positive again( two negatives make a positive)
{{{+7) }}}
The answer is "7"
.
Hope I helped,Levi
