Drag around vector , and the initial point of the new vector. Then, choose the scalar you want to multiply by, and drag the top slider to show the scalar multiple.
Then, answer the questions below, using the applet to try different cases until you convince yourself you are correct.

**Question 1:**For real numbers, we have a number 1 such that

**Question 2:**For real numbers, we have a number 0 such that

**Hint:**Be very specific in your answer. This is different from real numbers. Now, considering multiple additions is okay to visualize, but it would make it difficult to imagine when

**Question 3:**Create a definition for scalar multiplication.

**Hint:**Include the following explanations: - What changes, and by how much? - What stays the same? - What happens if

**Question 4:**Using your definition above, consider vector
