Answer

$12$

Work Step by Step

Solve using PEMDAS (The priority list for solving expressions: Parentheses, exponents, [multiplication, division], [addition, subtraction]. For the operations in the brackets, solve from left to right) $8\cdot [2^2+(6-1)\cdot 2] - 50\cdot 2 = 8\cdot [2^2+5\cdot 2]-50\cdot 2 = 8\cdot [4+5\cdot 2]-50\cdot 2 = 8\cdot [4+10]-50\cdot 2 = 8\cdot 14-50\cdot 2 = 112-100 = 12$
