Willow thinks of a number. She multiplies it by -9 and then adds 3.

If Willow's original number was 5, what number does she end up with?

Willow's original number = 5

After multiplying by -9, we get:
-9 * 5 = -45

After adding 3, we get:
-45 + 3 = -42

Therefore, Willow ends up with the number -42.

If Willow's original number is 5, let's calculate the steps one by one:

Step 1: Multiply it by -9.

5 * -9 = -45

Step 2: Add 3.

-45 + 3 = -42

So, if Willow's original number was 5, she will end up with the number -42.
