Let's solve the puzzle by first addressing the mathematical problems on the left side and then interpreting the corresponding grid on the right.

### Step 1: Solve each question

- **Q1: \(-61 + 80\)**
  \[
  -61 + 80 = 19
  \]
  So, the answer for Q1 is C.19.

- **Q2: \(-53 - 36\)**
  \[
  -53 - 36 = -89
  \]
  So, the answer for Q2 is D.-89.

- **Q3: \(29 + (-17)\)**
  \[
  29 + (-17) = 12
  \]
  So, the answer for Q3 is B.12.

- **Q4: \(-36 - (-15)\)**
  \[
  -36 + 15 = -21
  \]
  So, the answer for Q4 is A.-21.

### Step 2: Interpret the grid

The grid on the right assigns a symbol for each answer option (A, B, C, or D) in Q1 through Q4. The symbols are then used to create a code, with each row having a sum (4, 6, 9, and 0).

#### Key Symbols:
- **Hourglass** = A
- **Key** = B
- **Brain** = C
- **Lock** = D

### Step 3: Decode the grid

#### Row for Q1:
- The answer is **C (19)**.
- In the first row, **C = Brain**.

#### Row for Q2:
- The answer is **D (-89)**.
- In the second row, **D = Lock**.

#### Row for Q3:
- The answer is **B (12)**.
- In the third row, **B = Key**.

#### Row for Q4:
- The answer is **A (-21)**.
- In the fourth row, **A = Hourglass**.

### Final Code:
Based on the symbols:
- Q3 (B) = **Key**
- Q2 (D) = **Lock**
- Q4 (A) = **Hourglass**
- Q1 (C) = **Brain**

So, the final code is: **Key, Lock, Hourglass, Brain**.
