Simplify: `(-3ab)-(11ab)-(-20ab)-(14ab)`

Answer

To simplify the expression \((-3ab) - (11ab) - (-20ab) - (14ab)\), we can follow these steps:

### Step 1: Rewrite the expression
Start by rewriting the expression clearly:
\[ (-3ab) - (11ab) + (20ab) - (14ab) \]

### Step 2: Combine the like terms
Now, we will combine the coefficients of \(ab\):
\[ -3 - 11 + 20 - 14 \]

### Step 3: Perform the addition and subtraction
Calculate the sum of the coefficients:
1. First, combine \(-3\) and \(-11\):
\[ -3 - 11 = -14 \]
2. Next, add \(20\):
\[ -14 + 20 = 6 \]
3. Finally, subtract \(14\):
\[ 6 - 14 = -8 \]

### Step 4: Write the final result
Now, we can express the simplified form:
\[ -8ab \]

Thus, the simplified expression is:
\[ \boxed{-8ab} \]
