Let's break down the expression step by step:

Expression:  
\[
-40 + 5 + 3 \times (-4)
\]

1. **First, handle the multiplication**:  
   \[
   3 \times (-4) = -12
   \]

2. **Now substitute this back into the expression**:  
   \[
   -40 + 5 + (-12)
   \]

3. **Now perform the addition/subtraction from left to right**:  
   \[
   -40 + 5 = -35
   \]  
   \[
   -35 + (-12) = -47
   \]

So, the result is \(-47\).
