What is an instance when you might want to find an estimate

You might come upon a question that asks you to estimate the outcome of the equation.

For example : Julia has 10 balls because she gave Micah 10 , They are playing a game where each player has to give away ( subtract )5 balls until they are all gone , estimate the amount Micah will have when Julia is at 5.

I really hope that this helps you a lot.
