Question 107299
{{{2-(3(-4+1)*(9))}}}.....first add {{{-4+1}}}

{{{2 -(3(- 3)*(9))}}}.....then multiply {{{3}}} by {{{(- 3)}}}

{{{2 -((-9)*(9))}}}....then multiply {{{- 9}}} by {{{9}}}

{{{2 -(-81)}}}.........if you have {{{-(- 81)}}}, it will become {{{+ 81}}}

{{{2 + 81}}}.....add {{{2}}} and {{{81}}}

{{{83}}}...........this is a solution
