What does multiplication mean?

Multiplication is a fast way to do repeated addition. For example, $3 \times 4$ is the same as adding $4 + 4 + 4$.

In the problem $3 \times 5 = 15$, what is the answer $15$ called?

The answer to a multiplication problem is called the 'product'.

What is the Zero Property of Multiplication?

Any number multiplied by $0$ is always $0$. Or the 'product' of multiplication by $0$ is always $0$. For example, $100 \times 0 = 0$.

$$4 \times 0 = ?$$

$$0$$

$$0 \times 2 = ?$$

$$0$$

$$5 \times 0 = ?$$

$$0$$

If you have $3$ baskets with $0$ apples in each, how many apples do you have in total?

You have $0$ apples. This shows that $3 \times 0 = 0$.
