d. \( -49 \cdot 3= \) ?

When you multiply -49 by 3, you're essentially adding -49 three times. So, -49 + (-49) + (-49) gives you -147. Multiplying a negative number by a positive number always results in a negative outcome, so the answer is \( -147 \). If you're ever puzzled by simple multiplication like this, remember that the multiplication of a negative and a positive always leads to a negative result. You can visualize this on a number line where moving to the left (negative) represents the negative value being compounded. In this case, that means you're moving three steps left from zero!
