To solve this problem, we need to use subtraction and division operations.
First, we know that Reann gives half of her stickers to her friend, which means she keeps the other half. Let's call the number of stickers she starts with "x". After giving half, Reann has x/2 stickers left.
Next, Reann's brother gives her 8 new stickers. So, we add 8 to the number of stickers she has, which gives us (x/2) + 8 stickers.
Finally, we are told that Reann ends up with 12 stickers. We can set up an equation to represent this: (x/2) + 8 = 12.
To solve this equation, we need to isolate the variable x. First, subtract 8 from both sides of the equation: (x/2) = 12 - 8 = 4.
Then, to isolate x, multiply both sides of the equation by 2: x = 4 * 2 = 8.
Therefore, Reann started with 8 stickers.
