2D plus Delta
Okay kiddo, picture this: you and your friend are playing a game together where you both have a cookie. You want to know how many more cookies you have than your friend, so you count them. You notice that you have 2 cookies, and your friend has 1 cookie.
Now, let's add something called "delta" to the mix. Delta is just a fancy word that means "change." So let's say that you eat one of your cookies, and your friend gives away their cookie to someone else. Now when you count again, you have 1 cookie and your friend has 0 cookies.
But wait! You still want to know how many more cookies you have than your friend, even though the number has changed. This is where delta comes in. We use delta to show the difference between the original number of cookies and the new number of cookies.
In this case, delta would be 2 (the original number of cookies you had) minus 0 (the new number of cookies your friend has). So the difference, or delta, is 2 - 0 = 2. This means that you now have two more cookies than your friend.
So, in summary, 2d plus delta is just a way of saying that we want to know the difference between two values that may have changed. Just like in our cookie example, we use delta to help us figure out the difference between the original value (2d) and the new value.
