Let's solve the given problems step by step:

### 1. \( 5 - 4.999 + 0.795 \)
   - First, subtract \( 5 - 4.999 = 0.001 \)
   - Then, add \( 0.001 + 0.795 = 0.796 \)

   **Result:** \( 0.796 \)

### 2. \( 0.12 + 8.079 - 4.108 \)
   - First, add \( 0.12 + 8.079 = 8.199 \)
   - Then, subtract \( 8.199 - 4.108 = 4.091 \)

   **Result:** \( 4.091 \)

### 3. \( 0.12 + 0.001 - 0.007 \)
   - First, add \( 0.12 + 0.001 = 0.121 \)
   - Then, subtract \( 0.121 - 0.007 = 0.114 \)

   **Result:** \( 0.114 \)

### 4. \( 12 + 0.04 - 8.012 \)
   - First, add \( 12 + 0.04 = 12.04 \)
   - Then, subtract \( 12.04 - 8.012 = 4.028 \)

   **Result:** \( 4.028 \)
