Let's solve the problem step by step:
1. Reann gives her friend half of her stickers. This can be represented by division, as she divides her total number of stickers by 2 (since half means dividing by 2).
2. After giving half of her stickers to her friend, Reann's brother gives her 8 new ones. This can be represented by addition, as she adds 8 to her remaining stickers.
3. In the end, Reann has 12 stickers. This is the final amount, which can be represented by the equal sign (=).
To find out how many stickers Reann started with, we can work backwards using subtraction.
So, the operations needed to solve this problem are subtraction and addition.
