{[(-9)(-4)÷(-4)3]-1}25+107

Question

Need help with this, want to make sure i am using PEMDAS correctly, my answer was 207

Answer 1

Reading this as it is written, with no exponentiation, the order of operations yields

 

= (36/-12 - 1)25 + 107  

= (-3 - 1)25 + 107 

= (-4)25 + 107 

= -100 + 107 

= 7
