9 Bishop’s Simplified Method is like having a special recipe that helps you guess how long something will take to happen, just by looking at how much it has changed so far.
Imagine you’re baking cookies, and you want to know when they’ll be done. You check the oven once, and see they're halfway golden. 9 Bishop’s Method is like saying, “If they’ve turned half-golden in 10 minutes, then maybe they’ll be fully golden in about 20 minutes total.”
This method uses a simple idea: if something changes by a certain amount over time, you can figure out how long it will take to reach its full change, or how much it has changed so far.
How It Feels Like Magic (But Isn’t)
Let’s say you’re waiting for your favorite cartoon to start. You know the show starts 10 minutes after the movie ends. If you’ve been waiting for 5 minutes already, then you can guess that the show will start in about another 5 minutes, because it's halfway through the wait.
That’s exactly how 9 Bishop’s Simplified Method works, like a timer or a clock with a clever shortcut!
