37 + [-25 – (-11 + 19 – 4)] =

60 ÷ {2 · [-7 + 18 ÷ (-3 + 12)]} – [7 · (-3) – 18 ÷ (-2) + 1] =

-8 + {-5 + [(8 – 12) + (13 + 12)] – 10} =

Answer 1

$37 + [ -25 -(-11 + 19 - 4 )] \\ \\ 37 + [ -25 -(4 )] \\ \\ 37 +[ -29] => 8$


$60 /{2 * [-7 + 18 / (-3 + 12)]} - [7 * (-3)-18 /(2)+1]$

$60 /{2 * [-7 + 18 / -9]} - [7 * (-3)+9+1] \\ \\ 60 /{2 * [-7 + 2]} - [7 * (-3)+9+1] \\ \\ 60 /{2 * [-5]} - [-11] \\ \\ 60/2 * [6] \\ \\ \frac{60}{12} = 5$


$-8 + {-5 + [(8 - 12) + (13 + 12)] - 10 } \\ \\ -8 + {-5 + [(-4) + (25)] - 10 } \\ \\ -8 + {-5 + 21 - 10 } \\ \\ -8 + {6 } => -2$
