To solve this problem, we can use the operations of division, addition, and subtraction.
1. Let's say Reann starts with x stickers.
2. Reann gives half of her stickers to her friend, which is x/2 stickers.
3. After giving away half of her stickers, Reann is left with x/2 stickers.
4. Reann's brother gives her 8 new stickers. Thus, her total number of stickers becomes x/2 + 8.
5. Reann ends up with 12 stickers, so we can set up the equation x/2 + 8 = 12.
6. To solve for x, we subtract 8 from both sides: x/2 = 4.
7. Multiplying both sides of the equation by 2 gives us x = 8, which means Reann initially started with 8 stickers.
