Answer

$3+4[8(5\cdot5-20)-41]=-1$

Work Step by Step

$3+4[8(5\cdot5-20)-41]$ First, evaluate the operations inside the parentheses. Start by doing the product and after that, do the substraction: $3+4[8(5\cdot5-20)-41]=3+4[8(25-20)-41]=...$ $...=3+4[8(5)-41]=...$ Now, evaluate the operations inside the brackets. Start by performing the product and then the substraction: $...=3+4[40-41]=3+4[-1]=...$ Finally, evaluate the product and then the sum: $...=3-4=-1$
