Starting from `(-5) times 4`, find `(-5) times (-3)`.

Answer

To solve the problem of finding \((-5) \times (-3)\) starting from \((-5) \times 4\), we can follow these steps:

### Step 1: Calculate \((-5) \times 4\)
To find \((-5) \times 4\):
- We have one negative number and one positive number.
- According to the rules of multiplication of integers, when a negative number is multiplied by a positive number, the result is negative.

\[ (-5) \times 4 = - (5 \times 4) = -20 \]

### Step 2: Use the result to find \((-5) \times (-3)\)
Now, we need to find \((-5) \times (-3)\):
- Here, we have two negative numbers.
- According to the rules of multiplication, when two negative numbers are multiplied together, the result is positive.

\[ (-5) \times (-3) = 5 \times 3 = 15 \]

### Final Answer
Thus, the result of \((-5) \times (-3)\) is \(15\).
