The correct answer is "subtraction and multiplication."
To solve the problem, we first subtract half of Reann's stickers from the total number of stickers she ends up with, which is 12. This will give us the number of stickers she received from her brother.
Next, we subtract this number of stickers from the total she ends up with to find out how many stickers she had before her brother gave her 8.
Finally, we use multiplication to find out how many stickers she started with by reverse calculating the initial number.
