Question 512808
{{{ (-7) + 6 + (-(2-3)) }}}
The rule to follow when you have parentheses within
parentheses is -start with the innermost parenthesis
In your problem, the innermost is {{{ (2-3) }}}
which equals {{{ -1 }}}. Now you have
{{{ (-7) + 6 + (-(-1)) }}}
A minus in front of a parenthesis changes the sign
of everything inside, like this:
{{{ -( a - b + c - d) = -a + b - c + d }}}
So, now you have
{{{ (-7) + 6 + ( 1 ) }}}
Note also that if no sign appears in front of a number
then a + is implied
Also, you don't need the ( ) around the 1 or the 7
{{{ -7 + 6 + 1 = -7 + 7 }}}
{{{ -7 + 7 = 0 }}} answer
