Jess is right, it's add. 5 * 3 = 15. 5 * 2 = 10 and 5 * 1 = 5, 10 + 5 = 15.

To multiply 5 by 3, you can find the product of 2 and 5 and the product of 1 and 5 and add them.

Here is a step-by-step explanation:

1. Start by finding the product of 2 and 5. Multiply 2 by 5 to get 10.

2. Next, find the product of 1 and 5. Multiply 1 by 5 to get 5.

3. Finally, add the two products together. Add 10 and 5 to get 15.

Therefore, multiplying 5 by 3 gives you the answer of 15.
